Advice on adding class="reftest-wait" for tests with @font-face ; Ken Lunde's CSS[H|F]WOrientationTest.otf fonts

Hello,

http://test.csswg.org/source/css-writing-modes-3/text-orientation-mixed-vrl-100.html

http://test.csswg.org/source/css-writing-modes-3/text-orientation-mixed-vrl-100-ref.html

When I load the test (with the cache cleared), it takes on average 5-7 
seconds for the browser to fetch the font and then load it in the 
rendering engine (Gecko engine). If both test and reftest are loaded 
simultaneously, then such fetching and loading times should be the same 
for both files. So, I wonder if I should add class="reftest-wait" 
attribute into the document root element and into the reference file too 
and then remove it via script, like the documentation [1] states.

Q1: Should I add class="reftest-wait" attribute into the document root 
element and into the reference file too and then remove it via script?

And if I add class="reftest-wait" attribute into the document root 
element for the text-orientation-mixed-vrl-100 test, then shouldn't I 
assume that the font will be in the cache for the following tests (and 
associated reference files) also using the @font-face font:

http://test.csswg.org/source/css-writing-modes-3/text-orientation-upright-vlr-100.html

Q2: Should I assume the font will be in the cache for the following 
tests, therefore I would not need to add class="reftest-wait" attribute 
into the document root element?

I deeply believe and am convinced that we should just add
http://test.csswg.org/source/css-writing-modes-3/support/adobe-fonts/CSSHWOrientationTest.otf
http://test.csswg.org/source/css-writing-modes-3/support/adobe-fonts/CSSFWOrientationTest.otf
http://test.csswg.org/source/fonts/adobe-fonts/CSSHWOrientationTest.otf
http://test.csswg.org/source/fonts/adobe-fonts/CSSFWOrientationTest.otf
into that special "Fonts for CSS Testing" package
https://www.w3.org/Style/CSS/Test/Fonts/
and avoid all these reftest-wait trick. I think this is more convenient, 
it creates cleaner, clearer tests too.

Originally, the reftest-wait trick was aiming at overcoming delay and 
related load events in tests involving some kind of DOM manipulations 
and only for that purpose.

Comments, feedback, ideas welcome.
