 While testing the Block Editor in WordPress 7.0 RC1, a UI issue was
 observed where the "Regenerate Alt Text" button appears multiple times in
 the right sidebar.

 This occurs when navigating between different blocks, particularly when
 switching in and out of Image blocks. The button is duplicated instead of
 being rendered once per block selection.

 == Steps to Reproduce ==
 1. Open the Block Editor for a post or page.
 2. Insert or select an Image block.
 3. Navigate between different blocks (e.g., Paragraph → Image → Paragraph
 → Image).
 4. Observe the right sidebar (Block settings panel).

 == Expected Behavior ==
 Only one "Regenerate Alt Text" button should be displayed for the selected
 Image block.

 == Actual Behavior ==
 Multiple "Regenerate Alt Text" buttons are displayed in the sidebar.

 == Additional Notes ==
 - This may be caused by improper component unmounting or repeated
 rendering when switching between blocks.
 - The issue persists during the same editing session once triggered.

 == Environment ==
 * WordPress: 7.0 RC1
 * Editor: Block Editor (Gutenberg)
 * Browser: Microsoft Edge & Google Chrome
 * OS: Windows 11

 == Attachments ==
 - Screenshot showing duplicate buttons
 - Screencast video demonstrating the issue
