Bogdan,

Please check these max-height-percentage-003.xht and 
height-percentage-005.xht tests carefully; if they're okay with you and 
you want to be co-author of those 2 tests, that's fine with me. You'll 
have to register and sign up the W3C form [1] though to be co-author. 
... Hm... although I am no longer sure this process is still necessary 
as there is no mention of this in [2]

The closest test I could find was

http://test.csswg.org/suites/css2.1/nightly-unstable/html4/height-percentage-002.htm

and it was not as useful as your test.
