Pasting into shape group resizes grouped objects within

v7.9.12

I’m seeing strange behaviour when I paste shapes into a shape group, where all components within the group are all resized. Similarly, when you move objects outside the group bounds, the bounds expand, but when the group is repainted (visible toggle for example, or reload window), the bounds return to the originals and components are distorted. See screencaptures below. This has been a longstanding issue that I’ve had since maybe 7.7.
PS. Bandicam recorded my spotify :grin:
