On 1999-07-20-10-M9, Linux, apprunner or viewer, my home page (URL above) comes
up all black once the stylesheets are loaded.  This is a major regression.

Sure enough it does.

Is it possible for you to find a small example (without all the linked style
sheets) that reproduces the problem? I looked at it a bit, and it's not at all
clear what regressed and with so many people making changes this is going to be
very hard to track down

Thanks,
Troy

OK.  I'll look at it, but maybe not for an hour or two...

Simplified version is at (for now):
http://www.fas.harvard.edu/~dbaron/black

The problem only occurs after the reflow caused by the CSS Loader finishing.  I
*need* to link to an empty linked stylesheet to get the problem.  The position:
relative is the other piece needed.

This looks weird.

Thanks for the simplifying test case. I'll look at it today

Okay, I found the problem. It was a recently introduced regression (by me
actually), where I had a typo where I wrote '&&' when I meant to use '||'. That
caused the wrong type of frame to be created for the relatively positioned H1
element

Turns out it had nothing to do with the empty linked stylesheet.

The reduced case was a very big help. Thanks
