reduce number of FrameLoaderClient::didChangeScrollOffset calls
Created attachment 79786 [details]
In particular, it seems like the code that was around lines 550-560 here:
got lost in r76291. This results in lots of extra calls to FrameLoaderClient::didChangeScrollOffset. It turns out that chromium is the only port that implements this method (so that session restore can remember the page offset), so it's hard to test using DRT.
