Describe the bug
When the "Stop generating" button appears, the cursor changes to a text cursor (cursor: text) instead of a pointer (cursor: pointer) when hovering over it. Since the button is clickable, it should display a pointer cursor for better user experience.

To Reproduce
Steps to reproduce the behavior:

1. Start the application
2. Type a prompt in the textbar
3. Click on Stop generating button
4. Notice that the cursor appears as a text cursor instead of a pointer

Expected behavior
When hovering over the "Stop generating" button, the cursor should change to a pointer (cursor: pointer) to indicate that it is a clickable button.
