Jg experiment whitescreen

Whitescreen prevention PR

this PR aims to give an action to users who would normally entirely whitescreen to upgrade their browser. This doubles with preventing the load of the main app itself which should remove many impossible to fix errors or "noise" from our logs.

Goals:

1. Save money on datapoints from these errors
2. Give users an action to upgrade
3. Prevent a whitescreen (bad user experience)

Test plan

Use ngrok and test IE11 to make sure the browser doesn't entirely whitescreen
