Comment 24

[Hiroyuki Ikezoe (:hiro)]

Based on logs on several try runs, we have already the incorrect scroll position 0 at this line right after we got a scrollend event.

The reason why the scroll position is 0 at that moment is when we call this smooth scrollBy, the document has not yet finished loading. Then while we await scrollendPromise for the scrollBy operation, the document finishes its loading, thus a reflow is triggered via this FlushPendingNotification call in nsDocLoader::DocLoaderIsEmpty. Then the scroll container calls ScrollContainerFrame::TryResnap but at that moment, the smooth scroll operation has not yet reached to the destination, thus, it's clobbered by the resnap triggered by the reflow.

I think this is a pre-existing issue, I will file a bug (hopefully I can file the bug with a mochitest).

Anyways, I am going to do a workaround here.
