Description Ryosuke Niwa 2018-11-15 21:55:59 PST

Steps to reproduce:
 1) Go to drudgereport.com
 2) Click on  link (the link should replace the contents of the page)
 3) Scroll the new page
 4) Go back to drudgereport.com
About half the time, the page doesn’t completely paint.

I disabled PSON and couldn’t reproduce after trying a couple of times.

Is this testable?

I don't think so without significant effort. Would be good though, these things are very fragile.
