fast/scrolling/latching/scroll-div-no-latching.html is a flaky text failure on macOS debug arm64, failures appear as far back as test was introduced.

REPRODUCTION:
Reproduced on macOS 26.2 on arm64 debug TOT with the following:

run-webkit-tests --no-build --no-retry --no-show-results --exit-after-n-failures=1 --expect-pass --iterations=1000 --force -f --debug fast/scrolling/latching/scroll-div-no-latching.html

I am going to mark expectations as pass fail while this pends investigation.

It appears this test is flaky due to insufficient waiting for scroll completion. I put up a pr that resolves this. Please review.
