Build ID: 20150122214805

Steps to reproduce:

Consider the comment by Michael Vasquez's comment "No it wasn't." which is followed by two U+202E U+202E RIGHT-TO-LEFT OVERRIDE characters in utf-8 encoding. (Link to the stack overflow question containing the comment: http://stackoverflow.com/a/3314575/1671066)

Right click on the comment and select "Inspect Element (Q)".

Right click on <span class="comment-copy"> and select "edit HTML".


Actual results:

An text input box comes up and shows

<span class="comment-copy">No it wasn't.<naps/>


Expected results:

The final <span/> is backwards.

Furthermore one cannot position the cursor at the end of the line and erase <naps/>. (The cursor position seems broken)

I want to take back this part: "Furthermore one cannot position the cursor at the end of the line and erase <naps/>. (The cursor position seems broken)", since after more thinking I think the cursor moves correctly. It starts by moving left to right, then it switches to right-to-left.
