If I change the icon size in the main toolbar to 30 px, then I get three wrong resized icons as shown in attached image. Previously it was working fine.
I can confirm. Thos three icons all seem to stop responding to size increases after 22 px (I run with a 36 px toolbar space and 22 px icon size). If I drop the toolbar size down to 30 px with an icon size of 22 px, those three icons begin to be squished. FWIW, there are a ton of Scrivener restarts to do any of the testing for these changes.
