Update:

Enable debug mode for richNode, clean up the hard code hacking of disabling selection on focus for richNode (because it is solved in the latest reactflow by default, we no longer need to listen to keyboard event).

Known issues:

1. I suggest moving toggles in "site settings" into the right-click menu to make the sidebar looks more light.
2. nodes are re-rendered every time their position changes because xPos and yPos changes, causing a lot of overhead, which is even worse in richNode because we don't memo the editor.
   

Let's solve them in the future work if necessary.
