Mozilla trunk build 2000102221. If I have the following HTML: a<SPAN STYLE="display:none">b</SPAN>c and I select it with the mouse, the selection contains "abc" even though I can only see "ac" on the screen. This presents a security problem if I then paste the selected content somewhere (an xterm for example), since I may not be pasting what I think I have selected. It seems to me that selecting text should only select what the user sees...

Is this allowed by the DOM range spec?

Confirming for discussion.

See also bug 35148, style="text-transform: uppercase;" should copy as uppercase, possibly invalid. Mozilla currently matches IE's behavior for both display:none and text- transform:uppercase.

is this a possible duplicate of bug 39098?
