Content editable div badly behaved

[Avi Sternlieb]

Setting:

$('input').innerHTML = out;

has the cursor keep jumping to the beginning.

There are a lot of fixes on SO for this, but they make spaces act like <br> newlines for some reason.

So

$('input').innerHTML = out;
// SO accepted and highly voted function here
setCursorToEndContentEditable($('input'));

is also not working at all, but with a totally different issue. At least, not for the two answers I've tried.
