Preview remains empty on macOS Catalina #494

Hi, thanks for this useful package!

Unfortunately after a while of working fine, MPP suddenly shows strange behavior for me:

The Keybindings are still resolved as:

'atom-text-editor, webview.markdown-preview-plus':
  'ctrl-shift-M': 'markdown-preview-plus:toggle'

'atom-text-editor, webview.markdown-preview-plus':
  'ctrl-shift-X': 'markdown-preview-plus:toggle-render-latex'

but the preview tab that opens when pressing them is empty (just shows a black or white background depending on the syntax theme used). I get the same behavior trying to toggle it via the command palette and regardless of the backend I select.

I'm on a Mac running Catalina, on an older Mac running Sierra things were similar but a reinstall of MPP resolved the issue, not so on Catalina (I tried uninstalling and reinstalling from within Atom and via apm).

Atom : 1.47.0 Electron: 5.0.13 Chrome : 73.0.3683.121 Node : 12.0.0

Hmm, I can't really explain what happened, but after some more trial and error I reinstalled Atom using homebrew (brew cask install --appdir="/Applications" atom) and now things are working as normal!

Hi. You've apparently hit https://github.com/atom-community/markdown-preview-plus/issues/487. Atom v1.46 and v1.48 are unaffected, so homebrew probably updated to v1.48.
