Matrix editing shortcuts are not working

Description

Since version 0.59.0 Matrix editing shortcuts are not working.

Steps to Reproduce

1. run npm start

2. open http://localhost:8080/examples/basic/index.esm.html page

3. Type () and inside parentheses try to enter matrix editing shortcuts

   Shortcut	Command
   ctrl/cmd + Return/Enter	addRowAfter
   ctrl/cmd + shift + Return/Enter	addRowBefore
   ctrl/cmd + ;	addRowAfter
   ctrl/cmd + shift + ;	addRowBefore
   ctrl/cmd + ,	addColumnAfter
   ctrl/cmd + shift + ,	addColumnBefore

Actual Behavior

Nothing happens, the editor doesn’t react to commands.

No error in the console was thrown.

Expected Behavior

Commands were applied correctly to the matrix (e.g. adding row below on pressing ctrl/cmd + Enter etc. )

[Is this a regression: did it use to work in a previous version?] Yes, it worked correctly in version 0.58.0

Environment

Operating System [macOS, Windows, iOS. Include the version if possible] macOS, Windows 10

Browser [Safari, Chrome, IE, Firefox, etc…] Safari, Chrome, Edge

Yes, still on the to-do list…

These functions are commented out because they need to be rewritten to work with the new selection model. Getting selection in matrix to work (again) is leftover work from the implementation of the new selection model. It’s on my todo list.
