// On Safari, the final keydown event to dismiss the IME - which is the enter key - is also "Enter" below.
// Obviously, this causes problems because the final dismissal should _not_ submit the text, but should just
// stop the IME editing. This is the behavior of Chrome and Firefox, but not Safari.
//
// Keycode is deprecated, however the alternative seems 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.
