Very cool.

Did this actually fail before? I thought the timeout was 500ms. Also I hope this isn't flaky on contended bots... we'll see.

Thanks!

Oh, interesting -- when I ran it locally before my change, I got 1s (+2ms or so), so I set it to this value as the threshold. I don't think this will be flaky, since very little work is now done when preparing for data interaction, but if many other tests are running simultaneously and this isn't getting any execution time, another better way to test this might be to add hooks in the web view configs to disable the responsiveness timer altogether before beginning to spin the WP, forcing this test to time out if it does make a sync request to the web process.

I'll see how well the bots cope with this, and introduce some testing SPI with the above approach if I see any failures.
