Are there any plans to fix this? Are we OK always sending without modifiers
here?

This is the debate between two view points:

A: The concept of modifiers makes no sense for general composition event (e.g.,
consider voice input), so it should be removed for consistency.
B: We should make "best effort" to pass whatever's available in case the
developer has need for it.

The code is following A. While'd I prefer B, this seems to be more pain than
it's worth.

 
             // When typing, there is no issue sending KeyDown and KeyUp events around the
             // composition event because those key events do nothing (other than call JS
