Ended up copying [index.tsx](https://github.com/scniro/react-codemirror2/blob/master/src/index.tsx) to the project :(

* Go to the demo: https://uiwjs.github.io/react-codemirror/ * Focus somewhere in the code editor * Click `Ctrl + Z`. It empties the code editor It is happening for me on Safari/Chrome/Firefox...

Yeah, but it doesn't happen on CodeMirror demos (trying ctrl+z on these demo code editors, they don't do anything): https://codemirror.net/ https://codemirror.net/6/ General, why should `ctrl + z` should empty content?...

Apologies for the 2-year delay. This would limit the favicon to be .png, wouldn't it? I think it would be better to not have this, as all browsers default to...
