Entering `Mod+[` in Mac+Chrome triggers browser shortcut before key handling in prosemirror

[MH4GF]

Issue details

On Mac+Chrome, keyboard shortcut Mod+[ triggers browser shortcut before key handling in prosemirror, therefore, even if keymap is defined, it will open the previous page. This problem occurs only on Mac+Chrome, not on Windows+Chrome/Mac+Safari, etc. Other browsers will browser back if there is no valid command in the keymap defined by prosemirror.

Steps to reproduce

It is also happening in https://prosemirror.net/ Input a nested list like the one below, and entering Mod+[

- aa
  - bb<cursor>

Affected platforms

So far I found that only Mac+Chrome has this issue (tested on windows+chrome, mac+chrome/safari/firefox)

• [x] Chrome
• [ ] Firefox
• [ ] Internet Explorer
• [ ] Other

It looks like those keys only take effect when the ProseMirror bindings don't apply (i.e. when liftListItem or sinkListItem does nothing).

yeah, I understand that is the expected behavior, but Mac + Chrome seems to take effect browsers shortcut before ProseMirror bindings, even if applied.

What I'm saying is when I try this, that's not what happens.
