We should verify that we don't crash and do something reasonable

After talking to Sam, we still need to figure out the UX for this

Issue 631077 has been merged into this issue.

We should test this, but I don't think this will happen much in practice: the user would have had to open Chrome to install the WebAPK and go through the FRE. Right now we don't have backup & restore, so the only way I can see them getting the FRE is if they install it from Chrome, clear all of Chrome's data, and then open the WebAPK.

Tested this: you get the FRE when you open the WebAPK and then Chrome opens with the start_url. I continued to get Chrome with the start_url on subsequent invocations until I re-enabled WebAPKs in chrome://flags (lost this when data was cleared.)

Sounds like there's renewed interest in this. Sam: do you have pointers to the existing "short FRE"?

I don't think this is an important case for WebAPKs per #7, as long as it doesn't crash or do anything pathological. Sounds like that's the case per #8 so long as WebAPKs are enabled.
