* to only be to compare the timestamp from the onCompositionEnd event to
* the timestamp of the keydown event, which is not reliable. For
* example, this hack uses that method:
* https://github.com/ProseMirror/prosemirror-view/pull/44. However, from
* my 500ms resulted in far too long of a delay, and a subsequent enter
* press would often just end up doing nothing. A shorter time frame was
* also not great, since it was too short to be reliable (i.e. an older
* system might have a larger time gap between the two events firing.
