Did you ever figure this out? I read the attached post and looked at the figma file and can’t make heads or tails of it. I’ve set “hug” on everything I can think of and that does nothing. Here is my setup and sequence of steps.

The best I can figure is to clone and detach the icon set and create a new icon set that’s resized to start with. Then I’m swapping for icons of the same size and it works. But there’s gotta be a better way. Any help would be appreciated.

I have the same issue.
Instance swap + using a single set of icon component does not work.
I have tried every single possible combination and nothing stops it from resetting.

Same here

Hey everyone — really appreciate you all taking the time to weigh in with your experiences in this thread.

From what I’m seeing here, it sounds like the common issue is that changing the size of a button causes the swapped icon instance to reset to its original state. I did some testing and this appears to be tied to a known limitation: When an icon is swapped to a different size, Figma Design treats it as a different variant, and overrides tied to one variant don’t always carry over to another.

One solution that’s helped in similar cases is to build a single icon variant property across all sizes. This allows Figma Design to better preserve instance swaps when size changes occur, since it can stay within the same variant structure. For a refresher on this, have a look at this Figma Learn article: Create and use variants → Variant properties and values.

I realize this may not be the resolution you were hoping for, but I hope it helps acknowledge and clarify a bit more on the “why” behind the behavior.
