Don't generate pseudo element inside display:none.

We checked for non-null GetComputedStyle(), but it may also be non-null
inside display:none when ensured from getComputedStyle(). Skip
generating pseudo elements for that case. This caused a DCHECK failure
due to an incorrect marking for layout tree re-attachment inside
display:none.
