I'm tagging this as a bug report.
In Chrome for Android, the popup box for inserting images is broken. It jumps all over the screen; if you zoom out then you can see it, but as soon as you start typing it jumps put of view again.
Basically, the popup code needs a complete rewrite for mobile browsers.
Here's a screenshot:
You're using the website in desktop mode, right? The default mobile site doesn't have any formatting tools as far as I can see.
Anyway, in desktop mode, the image thinger pops up to the right but I can scroll over to it and use it just fine. I can upload and type URLs in there.
So no repro here, perhaps a screenshot or recorded video might help work out how to reproduce.
I was using an ancient version of Chrome, because... reasons.
Anyways, upgrading to the latest version fixed the issue.
