What's the current behavior?

1. Go to https://www.slatejs.org/examples/hovering-toolbar
2. Replace all content with just 'abc'
3. Select the 'c'
4. Press Cmd-B or Cmd-I
5. The app crashes

Debugging locally it seems to Editor.node(editor, point.path) in toDOMPoint finds the wrong node when looking for the domPoint of domFocus.

• Slate: 0.57.1 (latest)
• Browser: Chrome/Electron (keybindings don't seem to work in Firefox / Safari)
• OS: Mac

What's the expected behavior?

It should bold or italicize the c — the same behavior as pressing the formatting buttons in the hovering toolbar.

It seems that calling event.preventDefault() if handling the event seems to fix the error at least. I'm not sure if this is the right approach?
