🐞 Bug

What's the current behavior?

The first keypress of a german backtic fails to register an onChange event which creates different slate and dom points.

From sandbox: https://codesandbox.io/s/slate-reproductions-forked-m8qpg?file=/package.json

• delete default text until placeholder displays
• make sure MacOS german keyboard is enabled
• type a backtick (on my mac u.s. keyboard this is the "=" key)
• then type any other character

Editor crashes with error Cannot resolve a Slate point from DOM point: [object Text],1

This can also be reproduced in slate.js examples

Slate: 0.59.0
Browser: Chrome Version 86.0.4240.198 (Official Build) (x86_64)
OS: Mac 11.01

What's the expected behavior?

• The first instance of typing a german backtick should register an onChange event
• The editor should not crash when placeholder is enabled.

Seems like #3437 would solve this issue.
