Any reason why this shouldn't be display:none?

I did it because, we were using element.collapsed to hide elements in code,
according to collapsed attribute documentation:
https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XUL/Attribute/collapsed 
in CSS I used equivalent for the collapsed attribute thought that I should use
visibility attr to hide XUL elements, but I was wrong while the main purpose of
visibility property is different and in this case we should use display property
to hide XUL element.
Thanks for pointing.
