Bug 1767556 - Don't remove composing state when composition is started from first character. r=agi, a=RyanVM This occurs since newer GBoard's behaviour seems to be changed. When `GeckoEditable` receives text change from Gecko, it is possible to remove composing state if composition is started from first character. If Gecko's text change by IME, we shouldn't reset text state in `onTextChange`. `mCausedOnlyByComposition` means that this change is by IME.
