modal window = block handler?

[FlexibleLearning.com]

If you open invisible, then display it, a modal will not block. This
non-modal behaviour of a modal has been incredibly useful for displaying a
progress  indicator in a modal window. I do not consider it a bug as such
(modal blocks underlying windows, not necessarily code), and would hope this
quirk remains available. Otherwise we would need something like "go stack as
modal with messages".
