When debugging, the app will hang at the splash screen after Android reaps the background process and it is restarted

[aljohnston112]

I created an issue here: flutter/flutter#186294

The issue is reproduced like this:

1. Turn on "Don't keep activities"
2. Start a debug session with no breakpoints
3. Put the app in the background
4. Open the app
5. Get stuck at the dart splash screen
6. Add a breakpoint in main
7. The app loads

I tried to reproduce with a test app, but could not reproduce.
