[Javascript] See if item is hidden...

[Chris T]

I think Walter is saying this style is still set to display, but it's parent
is set to none, is that right Walter? If so, I would have thought the
display property would also cascade dynamically (since that's what the C
stands for in CSS), but maybe that's not the case. I've personally never
tested to find out.

If it doesn't update the property when the main parent's display property
updates, perhaps it's best to store which one is it's "parent" (not a true
parent since it's several nodes up) and check it's display property.  Of
course you could walk up the tree until you hit what would be its parent.
