Proposal for event ordering when inserting replacement text such as text prediction, spell checker, etc

[siliu1]

What is the issue with the HTML Standard?

writingsuggestions and spellcheck are attributes that control UA-provided writing assistance such as text prediction and spell checker. When user accepts a suggestion/correction, wrong order of events fired might confuse online editors which may produce unexpected results.

Here is a proposal that the order of events when inserting suggestions text:

Order:	Eventtype	inputType
1	beforeinput	insertReplacementText
2	input	insertReplacementText

The beforeinput event is cancelable. If it's cancelled, suggestion insertion should be aborted, and no input event is fired.

Composition events are not necessary therefore shouldn't be fired when inserting suggestions/corrections.

The proposal also applies to other suggestion insertions such as auto-correct, etc.
