continuing past this assert i get:

And then (4 times):

In another instance i chained to one of the other asserts, but not before
hitting and not catching a stack for (sorry):
###!!! ASSERTION: out of bounds: 'PRInt32(aIndex) >= 0 && aIndex <= length',
file i:/build/mozilla/layout/html/style/src/nsChildIterator.h, line 132

###!!! ASSERTION: prev sibling not in line list: 'Not Reached', file

Generally i'm deleting from top right to bottom left, but once i deleted from
bottom left to top right, and sometimes it doesn't assert. i can't really read
what is in the page (some unrelated amusing bugs) and it's repetitive anyway so
it wouldn't be useful for me to try to copy it.

The assertion was removed as part of Bug 562688.
