We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
[ISSUE]
**Title:** Data Summary Not Displayed in Status Bar When Loading Datasets

**Description:**
When a dataset is loaded using the OWDatasets widget, the status bar is expected to display a summary of the data, including the number of instances and variables. However, the status bar remains empty, preventing users from quickly viewing essential information about the loaded dataset.

**Example Code:**
```python
widget = OWDataSets()
widget.load_data('path/to/dataset.tab')
# Expected: Status bar displays something like "150 instances, 5 variables"
```

**Expected Behavior:**
After loading a dataset, the status bar should show a summary with details such as the number of instances, variables, and other relevant data information.

**Actual Behavior:**
The status bar does not display any data summary upon loading a dataset, leaving users without immediate insights into the dataset's structure and contents.

Please first localize the bug based on the issue statement, and then generate *SEARCH/REPLACE* edits to fix the issue.

Every *SEARCH/REPLACE* edit must use this format:
1. The file path
2. The start of search block: <<<<<<< SEARCH
3. A contiguous chunk of lines to search for in the existing source code
4. The dividing line: =======
5. The lines to replace into the source code
6. The end of the replace block: >>>>>>> REPLACE

Here is an example:

```python
### mathweb/flask/app.py
<<<<<<< SEARCH
from flask import Flask
=======
import math
from flask import Flask
>>>>>>> REPLACE
```
</solution>

Please note that the *SEARCH/REPLACE* edit REQUIRES PROPER INDENTATION. If you would like to add the line '        print(x)', you must fully write that out, with all those spaces before the code!
Wrap each *SEARCH/REPLACE* edit in a code block as shown in the example above. If you have multiple *SEARCH/REPLACE* edits, use a separate code block for each one.
[ISSUE]
**Title:** Data Summary Not Displayed in Status Bar When Loading Datasets

**Description:**
When a dataset is loaded using the OWDatasets widget, the status bar is expected to display a summary of the data, including the number of instances and variables. However, the status bar remains empty, preventing users from quickly viewing essential information about the loaded dataset.

**Example Code:**
```python
widget = OWDataSets()
widget.load_data('path/to/dataset.tab')
# Expected: Status bar displays something like "150 instances, 5 variables"
```

**Expected Behavior:**
After loading a dataset, the status bar should show a summary with details such as the number of instances, variables, and other relevant data information.

**Actual Behavior:**
The status bar does not display any data summary upon loading a dataset, leaving users without immediate insights into the dataset's structure and contents.

--- BEGIN ISSUE ---
[ISSUE]
**Title:** Data Summary Not Displayed in Status Bar When Loading Datasets

**Description:**
When a dataset is loaded using the OWDatasets widget, the status bar is expected to display a summary of the data, including the number of instances and variables. However, the status bar remains empty, preventing users from quickly viewing essential information about the loaded dataset.

**Example Code:**
```python
widget = OWDataSets()
widget.load_data('path/to/dataset.tab')
# Expected: Status bar displays something like "150 instances, 5 variables"
```

**Expected Behavior:**
After loading a dataset, the status bar should show a summary with details such as the number of instances, variables, and other relevant data information.

**Actual Behavior:**
The status bar does not display any data summary upon loading a dataset, leaving users without immediate insights into the dataset's structure and contents.

Please first localize the bug based on the issue statement, and then generate *SEARCH/REPLACE* edits to fix the issue.

Every *SEARCH/REPLACE* edit must use this format:
1. The file path
2. The start of search block: <<<<<<< SEARCH
3. A contiguous chunk of lines to search for in the existing source code
4. The dividing line: =======
5. The lines to replace into the source code
6. The end of the replace block: >>>>>>> REPLACE

Here is an example:

```python
### mathweb/flask/app.py
<<<<<<< SEARCH
from flask import Flask
=======
import math
from flask import Flask
>>>>>>> REPLACE
```
</solution>

Please note that the *SEARCH/REPLACE* edit REQUIRES PROPER INDENTATION. If you would like to add the line '        print(x)', you must fully write that out, with all those spaces before the code!
Wrap each *SEARCH/REPLACE* edit in a code block as shown in the example above. If you have multiple *SEARCH/REPLACE* edits, use a separate code block for each one.
