browser undo/redo greyed out doesn't match reality on Composer

Also the state of when the 'undo' menu action is available seems incorrect. Sometimes cmd+z works even when the undo menu item is greyed out(!)

I'm not sure this is something we can do about as Slate manages history itself instead of relying on the browser

You mean in the context menu? Is the 'undo' state displayed anywhere else?

I believe thats what is meant yes
It is not currently shown but it could be as per: https://www.slatejs.org/#/history

(I meant in both the context menu and in the normal menu bar menu)

I can't reproduce this issue. If anyone knows how to, please add steps and reopen.
