Ace and IE: editable content cutting off at 2nd line of code

Question

Edit SOLVED: Initially I got under the impression that Ace will be completely unusable due to editable code cutting off on 2nd line. So I thought 'let's not even load it in IE'. Turns our the bug was fixed, Ace works just fine in 9 (or close enough, not quite as nice as in FF or Chrome though).

ORIGINAL QUESTION: I find myself having to prevent Ace editor from loading in IE and wonder what specific browser features need detection? Trying to avoid browser sniffing.

Answer 1

Browser feature detection can't work for this, because ace already does feature detection, and when it's broken, it's broken in a rather subtle way, because of a bug in ace code, not because of missing browser features.

So the best way is either to report a bug or use browser version sniffing.
