sideBySideFullscreen: false > Uncaught TypeError: Cannot read property 'className' of undefined

[Offerel]

If i set sideBySideFullscreen: false and i click the side-by-side icon, i get a error message: Uncaught TypeError: e is undefined

Steps to reproduce the behavior:

var mde = new EasyMDE({
            element: document.getElementById('md'),
            autoDownloadFontAwesome: false,
            spellChecker: false,
            autofocus: true,
            status: false,
            promptURLs: true,
            sideBySideFullscreen: false,

• load the editor in a browser
• Click the side-by-side button
• in JS console Uncaught TypeError: e is undefined is displayed

Expected behavior SideBySide view is opened not in fullscreen

Version information

• Browser: Firefox 84.0.2
• EasyMDE version: 2.13.0

The error message has now changed (at least in Chrome) to Uncaught TypeError: Cannot read property 'className' of undefined

I too have recently come across this. Seems to happen for me when I have more than one instance of EasyMDE on the page where I'm attempting to use Side-By-Side.

In EasyMDE version: 2.14.0 the issue is solved. Many thx.
