Messenger style issues
Summary
This MR changes the form toast container so it only renders when there's visible toasts and fixes the z-index issue that caused the navigation sidebar to appear on top of the conversations
Closes #3133 (closed)
Steps to test
- Open a messenger conversation, make sure the window is ~1350px wide
- You should be able to type a message
- Set the window's width to 565
- The conversation should appear on top of the sidebar
Estimated Regression Scope
There's the remote possibility that it could break form toasts, although I've tested it and it works fine
