User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36 Edge/15.14999

Steps to reproduce:

Go to https://tc39.github.io/ecma262.
Scroll the page down using the mouse wheel past clause 4.

Does not repro in Nightly. E10s is not enabled.


Actual results:

Page blanks, becomes unusable.


Expected results:

Should be usable.
Also doesn't seem to repro for me if I scroll by dragging the scroll bar.
reproduced on OSX.

regression range (firefox 42):
  https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=8e5c888d0d89&tochange=1f77b78797d6

before the regression, scroll or redraw stops on similar situation, but at least there wasn't blank page displayed.


fixed in the following range, either bug 1269045 or bug 1269046:

Any thoughts on whether there's a targeted fix we could take for 51 here, Mats?

Uplifting bug 1269045 and/or bug 1269046 to v51 is too risky IMO.

Thanks, Mats. Calling this fixed on 52+ then.
