Subject: [PATCH] keep the insert symbol popup open across decoration-only
 transactions

The realtime spelling plugin dispatches an updateSpelling transaction 100ms
and 5s after the editor is first focused, whether or not realtime spelling
is enabled. InsertSymbolPlugin closed its popup on every plugin view update,
so an Insert Emoji / Insert Unicode popup still open at the 5s mark vanished
mid-typing. Only close the popup when the document or selection changed.

(cherry picked from commit bef48d7baee4452033c2e347d798dfeea2b75c4e)
