We lock the screen to stop it closing before we open our window, and unlock it when the window is open (the window is a sufficient lock). However we were not resetting the flag indicating the screen was still locked, so it was getting unlocked twice.
The PSMTabController framework was calling mouse exited events on its
rollover button implementation which caused an inifinite recursion in
event forwarding.
In CSS 2.1 this was undefined.
CSS 2.1 -- 12.1 The :before and :after pseudo-elements
Note. This specification does not fully define the interaction
of :before and :after with replaced elements (such as IMG in HTML).
This will be defined in more detail in a future specification.

In CSS 3 the :before and :after generated content boxes are not allowed
on replaced elements.
CSS 3 Generated and Replaced Content Module
12. Replaced content
The box model defines different rules for the layout of replaced
elements than normal elements. Replaced elements do not have
'::before' and '::after' pseudo-elements; the 'content' property
in the case of replaced content replaces the entire contents of
the element's box.

This is a patch for Mantis issue 2170.
The bug is that, if you hover over a link in a window and then close
the window with Control-F2, the pointer remains as the link pointer
shape. The fix restores the pointer to the default shape before
destroying the window.
Now we only look for hints that are actually possible for the
given element. This new way of doing things is made possible
by the new LibCSS API for hints.
This also makes use of the LibDOM HTMLElement tag type to avoid
lots of massive if-else-if ladders of dom_string_caseless_isequal
calls.
Collect hints and provide them up front.
Note this implementation is minimal effort, and quite inefficient.
We can be faster about it by walking the element's attributes, and
caching things set on ancestor elements which apply to the current
element. (Mostly table, and body stuff.)
