model.canUndo is not a function

Hello. When I usereact-router-dom with react-monacoeditor I get this error.
The error will appear when I refresh (F5) the page which contains the editor and navigate to another route (/about) and back to editor page, the editor stops working and I get this error.

@varghasabee Can you give me example debugging?

[sabolch]

Yes, of course

and on codesandbox

@varghasabee I found that the dependency package may be too old and cause an error.

The following example can be run:

I'll try it out. Thank you!
