ProseMirror: The ProseMirrorKeyMaps plugin and internal implementation doesn't respect multiple open editors

[typhonrt]

What happened?

The internal handling of the ProseMirrorKeyMaps plugin is always active for the last editor to be opened even if it isn't the current actively selected editor. A quick way to see the symptoms is to open two editors and in the attached video item A is opened before item B. Go back to item A and hit Ctrl-S to save and Item B is saved. Hit Ctrl-S again and errors will be thrown as Item B is still the target of the internal PM implementation.

While this issue pertains to key mapping there may be other internal state aspects to prosemirror.js / PM implementation that doesn't play nice w/ multiple editors open.
