Weird effect on arstechnica when scrolling to the top (OMTP)

(1 file) scroll (mouse wheel or scroll bar) away from the top, then scroll all the way to the top.  With the scrollbar, the text in the first paragraph is black "bounding box" rectangles until I let go of the mouse button.

I'll look for a regression range.
What OS and version did you see this on?
This is Windows 10, and it feels like it's something that the site is doing (e.g., looks like what facebook does when they're loading.)  Not successful with mozregression so far, so I'm not sure how actionable this would be.
This page has also gone to "spinning forever" at times, and I also managed to get the boxes to be white/not show.  The boxes are per line of text, not per word.
I am, however, running OMTP enabled, let me see if that makes a difference.
OMTP only.

Backout by
Backed out changeset 8cd211d1292e for unexpected passes on quantumrenderer, e.g. in reftest layout/reftests/counters/counter-suffix-ref.html. r=backout
So I fixed one of your bugs, could you reland this marking the relevant QR tests passing?

I did this, since I had to update the webrender reftest tracking spreadsheet anyway.

Try push to verify greenness:

Will land if that looks good.
