Hey @masteradhoc, thank you for opening this PR!

Please could you add some testing instructions for this, and please add before/after screenshots if possible since this is a visual change.

We use these notes and screenshots in our release process so it's important to have them.

By the way it's probably fine to copy the reproduction steps from the issue but change them to reflect the updates you've made. I'll review and run CI for this PR tomorrow.

Thanks for the PR! Nice work. It works for me, and CI is passing in #10291

I updated your description to show the after image, updated the last step of the testing notes, and also added a changelog entry.

Thanks again! 🥂
