Looking at a recent Linux64 debug run, this is one of the 5 most common sources of warning spam, with 175,940 instances:
WARNING: '!scrollbar', file widget/Theme.cpp:1103
Like the other widget warning issue I filed, it appears to happen very frequently in a limited number of tests.
In one log I looked at, this warning happened a total of 74 times, but only in two different tests:
dom/indexedDB/test/test_third_party.html
toolkit/components/passwordmgr/test/mochitest/test_submit_without_field_modifications.html
Searching across all of the logs from this run, the log where this happened the most was debug-web-platform-tests-swr-nofis-13_wpt13, where the warning occurred a little over 7000 times. Judging by the extremely purple bar when I try searching for it in the log, most of these are occurring in the test:
/fetch/api/response/response-static-redirect.any.worker.html
It looks like this warning was added in bug 1764435.
Emilio, is this warning worth keeping around or is there something we can do to reduce the frequency? Thanks.

This is actually a bug that causes a rendering issue on macOS.

The scrollcorner isn't a child of a scrollbar so we don't find it.
Instead, check for the scrollable node. This info is only used on macOS,
this fixes the rendering of rtl scrollcorners with non-overlay
scrollbars, e.g.:
<div style="border: 1px solid; width: 100%; height: 100%; overflow: scroll; direction: rtl"></div>
Or so.
