There's a lot of changes going on here which makes me nervous to include it in 6.6. What is the minimal fix without improving anything else? |

I dropped the changes that improved anything else. There are alternatives approaches that could be more minimal. Here’s one that I didn’t prefer because there’s more coupling (some of it cross-package) when ideally none of these components have to concern themselves with each other. Also, it uses diff --git a/packages/edit-post/src/components/layout/style.scss b/packages/edit-post/src/components/layout/style.scss

Here’s one I like better. It’s encapsulated and two birds with one stone because it also fixes #62639 but would probably create the same caution for 6.6 that some folks had about #62681. diff --git a/packages/editor/src/components/visual-editor/style.scss b/packages/editor/src/components/visual-editor/style.scss

[Feature] Zoom Out
Backport to WP 6.6 Beta/RC
|
Would love some opinion from CSS experts (maybe @jasmussen or if you know someone else 😃) |
|
Okay, I realized there was one more thing this was still doing besides fixing the double scrollbars and pushed a commit to revert that. Now it’s about as minimal as any of the alternative solutions I mentioned. What this was doing besides was allowing horizontal overflow when not zoomed out. That was so that if a device preview overflows horizontally it’s not clipped and can be scrolled. It seems like an oversight when zoom out was added but it’s probably a minor concern. I removed the zoom out label since now the changes don’t touch anything related. |

The one thing I originally included in this PR that I think might qualify to include is fixing the triple scrollbars that appear in the post editor in device previews. I mentioned it in the issue #62319 (comment). It is not present 6.5 so also a regression we’d ideally fix for 6.6. It can be done simply: diff --git a/packages/edit-post/src/components/layout/style.scss b/packages/edit-post/src/components/layout/style.scss

I don’t really see it as a separate issue but I'll put it in separate PR if that’s what others think is best. |

Thanks for the ping. Based on the most recent changes there's not a lot of CSS, so it might be safer now. In a quick surface test this seems to work as intended, though I had a hard time replicating the double scrollbar in trunk myself. It's a hard one to test deeply, while these are indeed sensitive rules, it's also hard to foresee every side effect. It seems fine given its current small footprint. |
|
I also can't reproduce the original issue. 🤔 |
|
Which browser are you using? |
Maybe it depends on having OS preferences so that scrollbars always show. I would think it doesn’t but maybe it’s hard to tell that there are nested areas of overflow without. I'm using Chrome/macOS. |
|
In my environment (Windows OS, Chrome), I can consistently reproduce this issue by following these steps. If you're on a Mac, you may need to change your OS settings to always show the scroll bars.
I have confirmed that this issue is resolved in this PR. 6174b6412f8ad477bcdc95134692ec83.mp4 |

#62894 resolved this nicely so I'll close. |
