[Editor] Typing results in missed letters. Select All fails.

While the grav admin plugin is responsive, the editor it uses doesn't fully support mobile.

If I try to edit any page that has text greater than the scrollable text box in Android, *Select All* fails. It only selects what is visible on screen.

Also if I type really fast and backspace occasionally the caret jumps to the wrong spot and text gets erased or missed. I presume its because of the insertion of auto-correct letters not being anticipated by the key handler.

Notably githubs text box (here) works fine, so does wordpress' app, so its just a grav text box issue.
