Duplicate "Regenerate Alt Text" button appears in Block Editor sidebar when navigating between blocks - WordPress 7.0 RC1

[torontodigits]

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

• Screenshot showing duplicate buttons

Hi and welcome to WordPress Core Trac!

Please identify which plugin you use for the AI alternative text generation. There are multiple ​matches in the plugin directory. The issue likely should be reported to the plugin author.

Also, the pattern in the screenshot and video is 'Offset images with descriptions', which supplies the alt text for both of its images.

@sabernhardt good catch! Its Open AI plugin & best place is to report on respective [Github repo]​https://github.com/WordPress/ai-provider-for-openai.
