@Born2Phil Thanks! Definitely something related to using css transforms.
Though I’m curious why transform properties on the child, somehow affect the parent div/iframe…
A cursory google search shows that %s transforms are probably the culprit. I’m guessing a ton of fractional values are bugging out…
I’d like to continue using transforms (I use them for animations), I guess I’ll have to step away from edge touching extensions until I can figure out a fix.
