Hitting "Cancel" on "Are you sure?" box bugs out the interface

[susodapop]

Issue Summary

Users on a laptop who accidentally make a "back" gesture can lose work because of this bug.

Steps to Reproduce

1. Click "New Query" from the New menu
2. Write a query (don't execute it).
3. Hit the back button in your browser
4. When prompted about losing changes, hit "Cancel"
5. Observe the interface shrinks, the query disappears

The behavior is unpredictably different. Sometimes the interface shrinks but the query is still there, just near-impossible to see. Other times the "Page Back" operation proceeds normally and the query is just gone. In rare instances I've had the entire page crash and show a generic "Couldn't find that page" error. I can't get this to reproduce, however.

Oddly, executing a query without saving it does sometimes avoid this behavior. Not always, however.

It's SaaS only issue because we use a fork of the AppView component there that we never fixed this issue in. It will be resolved as part of the React migration.
