I don't know why there's this difference...
It isn't related to this patch for sure.
The image is a bit complex so it's hard to debug something.
I do wonder if it could be due to a small variation with a floating number.
What puzzles me is that locally, if use the magnifying glass from devtools to get the color code, they look exactly the same when I take page 13 in tracemonkey compared with the extracted page.
