Uh oh! @jonrohan, at least one image you shared is missing helpful alt text. Check your pull request body to fix the following violations:

• Images should have meaningful alternative text (alt text) at line 5

Alt text is an invisible description that helps screen readers describe images to blind or low-vision users. If you are using markdown to display images, add your alt text inside the brackets of the markdown image.

Learn more about alt text at Basic writing and formatting syntax: images on GitHub Docs.

Pull request overview

This pull request reverts PR #7427, which had changed the styling of ActionList items with inline descriptions. The original PR attempted to fix overflow issues by changing the layout from flexbox (flex-direction: row) to block display, but this revert restores the original flexbox-based approach.

Changes:

• Reverts CSS styling changes for inline ActionList item descriptions back to using flexbox layout
• Updates visual regression test snapshots to reflect the reverted styling
• Removes the changeset file that documented the original change
