Set release status flags based on info from the regressing bug 1270059

:jesup, since you are the author of the regressor, bug 1270059, could you take a look? Also, could you set the severity field?

For more information, please visit BugBot documentation.

Very likely a broken page, since the deferring of timeouts until idle is within spec. I'll pull a profile to check

[Randell Jesup [:jesup] (needinfo me)]

The page hard-loops while loading, using 100% CPU doing image-sets mostly. This leaves no idle time, so timeouts don't run, and it won't finish loading without a timeout. It's being a very bad page. That said, it's possible we could handle this a little better, by giving a maximum deferral time for timeouts.

smaug: perhaps limit deferrals to N seconds? 5 seconds without idle past the timeout -> run anyways? (probably a pref. And is 5 too low or too high?)

I guess that could work. We could even reuse this pref, https://searchfox.org/mozilla-central/search?q=page_load_deprioritization_period%28%29&path=&case=false&regexp=false
