Zoom is janky and crashes on iOS

Hi! When I try to zoom in/out on iOS app it is jittery. Zooming in especially crashes the app (and on the web browser it refreshes and errors out with a “problem repeatedly occurred”)

can repro on ios, will look into.

note to self: probably releated to a newly added/expensive window resize event handler

this is impossible to properly debug because ios safari doesn’t log any errors when pages crash like this. Instead I’m applying a bunch of speculative fixes based on javascript - Debugging a iOS Safari crash "A problem repeatedly occurred" - Stack Overflow that do seem to address the problem in my testing

Thank you! Just tried zooming in and out aggressively and spaces don’t crash- can post here if I run into it again
