specifically playing w/ the toc in help

Comment 2

[Boris Zbarsky [:bzbarsky]]

Hmm... I can see this happening for subframe loads (the content viewer will
disable refresh for the whole viewmanager tree, and we may already have a
pending invalidate event).

Perhaps invalidate event firing while refresh is disabled should simply cause
the invalidate event to be reposted?  Or silently ignored, since we plan to
reenable refresh and post another invalidate event?

In Bug 545593, the assert was changed to:
  NS_ASSERTION(IsRefreshEnabled(), "Cannot process pending updates with refresh disabled");

Which was in turn removed as part of Bug 598482.
