:emilio, since you are the author of the regressor, bug 1940412, could you take a look?

Flags: needinfo?(emilio)

Do we know which patch of that bug caused it? The last one I guess?

Hi, yes, the last patch : https://hg.mozilla.org/integration/autoland/rev/237b55e3c403 is the most likely to have caused this , as the contents of IMEContentObserver.cpp have been modified.

Flags: needinfo?(amarc)

Hmm, did you set the regressor range after retriggers? The change to IMEContentObserver there doesn't change any behavior (just adds an argument to a function).

I don't see anything in that patch that could've caused this. Any chance you can confirm this was retriggered / found as the culprit?

Alternatively... Makoto, is there anything that could've caused this recently? It seems BeginInputTransaction(mDispatcher) is probably unexpectedly failing?

According to backfills and retriggers, it seems that something else caused this failure, apologies for the confusion.

I guess that this issue is IMEContentObserver.

Actually, I don't have reproduced step for this assertion. But I guess that this might occurs when widget side (GeckoEditableSupport) calls several selection update requests into 60Hz. IMEContentObserver wants to merge several text requests, but it cannot seem to handle multiple selection update requests...
