"Keyboard Shortcut" menu gets open (and doesn't close) when typing a question mark in the slide text.

Is this a hackmd.io issue?

• [X] Yes, the bug happens on https://hackmd.io
• [ ] No. If it's a self-hosted CodiMD instance, please fire up the issue in the repo of CodiMD: https://github.com/hackmdio/codimd

What's the problem

During slide creation, shortcut menu gets opened, and doesn't get closed.

Current behaviour

Typing a slide text that contains a question mark the "Keyboard Shortcuts " menu permanently.

Provide steps to reproduce:

1. Start a hackmd document, with "slides" preview:

   ---
   type: slide
   ---
   

2. Write a line with a question mark

   Is this a slide?
   

3. Outcome: the "Keyboard Shortcuts" menu open, and hide the slide text.

Expected behaviour

The shortcut menu should disappear when moving to another slide, or typing more text

Environment

I use HackMD on:

Desktop

• OS: [macOS]
• Browser: [chrome]
• Browser Version: [71]

Workaround

Currently, the only way to close this dialog is to typing another question mark (and delete it) - but that is a bit counter-intuitive.
