(Tested with both)

See http://forums.mozillazine.org/viewtopic.php?t=75003 for some more
information (also where I got the testcase from)

It seems that text that is displayed inline with position:relative set on it
does not allow proper selection. Only one line of text at a time can be selected.

I put this under Selection, but it might go better in one of the CSS components.

Attachment: Testcase

This testcase was made from the mozillaZine forum post I linked above. If you
try to select the text from outside the border it works, but selecting within
the border will only work one line at a time.

I wonder why the positioning and display affect this... is this a
GetFrameForPoint issue or an issue with the ranges?

I get the described behavior in Windows XP so its not just linux.

This behaviour has been observed to occur in both Linux(Debian) and Win98SE.
Also as pointed out in the second
page(http://forums.mozillazine.org/viewtopic.php?t=75003&start=15) of the
Mozillazine forum thread, if one tried to highlight the text from outside the
block element of code(for URL provided as test case), the highlighting goes
bezerk and you end up highlighting almost to the end of the page.

All show same behaviour.

OS -> ALL based on comments.

Notes:
 -- if you start the selection from outside, it works -- all lines can be selected
 -- if you start the selection on a line, it gets trapped in that line

[Robert O'Callahan (:roc) (email my personal email if necessary)]

This is really simple. Currently selection is confined to a view. When you click
with the mouse, mouse capturing is set to the nearest view enclosing the
clicked-on frame. As you drag, that view continues to capture mouse clicks. So
dragging outside the view won't select any more text.

The real fix is in bug 53966, where I make mouse clicks only capture to the
nearest *scrolling* view. But that fix is blocked by a dependence on dbaron's
work on generating synthetic mouse events to handle updates of the mouse state
in response to layout changes.
