[Test] [Mobile] Keyboard behaving strangely on smartphones

[immutablestate]

In the mobile version, keyboard input behaves strangely. When typing a capital letter, the cursor position jump backward by one position in some cases. This leads to the following input

Professoren ⨝ Vorlesungen

being turned into

Professoren ⨝ orlesungenV

Cannot reproduce with Android 9, Firefox 68.8, Google Keyboard.
Might be related to codemirror/codemirror5#6145 and codemirror/codemirror5#5844 and eventually will be solved with CodeMirror 6.

The only Issue I experienced (with firefox) is, that after entering multiple words, hitting (and holding) backspace will reposition the cursor to another word.

@mmayerl please tell OS, tested Browsers (at least chrome, firefox), Keyboard and if this also happens without the join symbol.

I am using EasyMDE which uses CodeMirror and on Android phones, when typing a space, the cursor shows the space being typed, then the cursor jumps back deleting the space. This only happens on Android on-screen keyboards. When I use a physical bluetooth keyboard, this does NOT happen. Also, I'm using Chrome in Android 10. Another thing that I noticed, when I type a second space, it works. Of course, it only renders the second space since the first space was deleted.
