Automating IME Input

[alexkeng]

just want to bring the awareness to a project that we have been working on for automating IME input. This project can address the pain point where currently web authors don't have a way to simulate IME input and write tests for scenarios that involve composition events.

Here is a 11min introduction video about the project (presented by our summer intern Javier):

If you are interested, please take a look and we can discuss any feedback or comments here

Thanks!

I think this should be supported by WebDriver's action for making it testable in WPT simply.
