I tried to reproduce the issue and encountered the same problem.

I am also able to replicate the issue on WordPress 6.6.2. This issue is not there on WordPress 6.7 Beta 1.

I would agree with @nithins53 not seen with WordPress 6.7 Beta 1

Thanks, everyone, for testing this! I was also able to reproduce this in Chrome for 6.6.2 (using Playground or a local install), but not in 6.7-beta, as confirmed by others above. Safari and Firefox did not produce the issue in either version.

As this seems to only affect 6.6, I've moved it into the 6.6.3 milestone for consideration. The minor release squad ​will monitor reported issues to determine if and when another minor might be released. I'll also raise this ticket in the #6-6-release-leads channel.

Environment

• Hardware: MacBook Pro Apple M1 Pro
• OS: macOS 14.6.1
• Browser: Safari 17.6, Google Chrome 129.0.6668.91, Mozilla Firefox 130.0.1
• Server: nginx/1.27.1 / PHP: 8.3.12 / MySQL: 8.0.27 AND WordPress Playground
• Theme: twentytwentyfour v1.2

Test Playground Links (compare Chrome with other browsers)

• ​Playground 6.6 ❌
• ​Playground 6.7 beta ✅

Based on the testing results above, it seems this is no longer an issue in 6.7 and the issue is also intermittent.

There are currently no plans to have a 6.6.3 release at this time. And with RC1 for 6.7 happening in a few hours, I think it's best to just close this out as wontfix.

If this surfaces as a larger problem than it currently presents as, we can reopen this and reconsider.
