Description Simon Fraser (smfr) 2020-04-01 10:53:31 PDT 
Repeated scrolling in a nested scrollable area (like an iframe) sometimes fail to scroll the iframe, after the fix for bug 209790.

This happens when the new scroll has small x and y deltas that make it hard to determine which is the major scrolling axis.
