WordPress Dashboard Collapse Menu Transition issue.

Hi
When I collapse the menu it's showing awkward.
See the video: ​https://d.pr/v/34K9H4
I think this issue should be fixed as soon as possible.

Thanks for the report!

The icon dimensions have a discrepancy between the expanded and collapsed states. The expanded link's height increased by 0.2 pixels in [45186], and the width had a 1-pixel difference before then. This is more noticeable on the About pages than any page where you would find an open submenu on the side (because expanding a submenu is a bigger difference).

• When the menu is collapsed (or "folded"), the icon is in a 35px by 30px container within a 36px by 34px link.
• When the text shows, the icon's container is 36px by 34px, and the text size makes the link 160px by 34.2px (14px times 1.3 line-height plus 8px padding on the top and bottom).

During test triage, it was agreed to mark this ticket's priority to low, but keep it open for a patch. Why low? Triagers noted that the sub-pixel shift was barely noticeable. However, the assessment in comment:1 is a good basis for a patch.

Adding has-screenshots as reporter's video does show the shift.
