Test for failing gracefully in lack of browser features #27734
Description
Your use case
We could have a test that ensures the graceful failures screen appears if the browser doesn't support features we need (ie. the modernizr check fails). This would cover:
- Us correctly doing the modernizer check as the first thing we do (eg. no stray react-sdk imports creeping in before the modernizer check)
- The screen looking like it should (screenshot test?)
- Modernizr generally working
Have you considered any alternatives?
