When you press the button to choose a new costume in the costume editor, it will still show the popup if you leave the costume selector.
The popup even appears if you actually create a new costume.
The popup in question is the one saying Choose a Costume which appears when you hover your mouse over the button.
Here is a project demonstrating the bug.

I can confirm this! It seems like the ‘on mouse out’ trigger for the tooltip is failing to fire when the library overlay opens or when a new asset is generated.

A couple of questions to narrow it down: > 1. Does it stay on the screen indefinitely until you hover over it again?
2. Does it happen with the ‘Choose a Sprite’ or ‘Choose a Backdrop’ buttons too, or just Costumes?

Providing those details helps the Scratch Team figure out if it's a global UI bug or specific to the Paint Editor code!

Can replicate with choose a sprite, backdrop, and sound

Doesn't seem intentional bc when I hover over the button again, it looks like there's two popups on top of each other. When I hover off after that, both disappear

2 - It also happens to backdrops

Try hovering over the magnifying glass, and then hover over one of the other menu options, and it's easier to notice that there's two of them
Anyway, that reply sounds like AI
