[css-flexbox] Reporting interop issues when you don't know which implementation is right?

While using flexbox in anger, I've encountered interop issues on scarily 
simple cases:

http://jonrimmer.github.io/flexbox-interop/fixed-height-container.html
http://jonrimmer.github.io/flexbox-interop/nested-flexbox-in-fixed-height-container.html

Both appear quite different in Chrome vs. Firefox.

As a developer, it's unclear how to proceed when you find problems like 
this. Is Chrome correct? Is Firefox? Are these known issues? Are there 
already bugs raised?

Initiatives like Test The Web Forward[1] provide guidance on writing 
tests and raising bugs against non-conforming browsers, but it isn't 
clear what developers ought to do when they don't know which behaviour 
is correct; they just discover an inconsistency.

What is the best place for questions like these? They seem to fall 
inbetween the kind of standards-usage issues suited to forums like Stack 
Overflow and standards-design issues suited to www-style. Maybe there's 
a need for a third forum? Such as WG-run GitHub projects focused on 
interop for particular specs, where developers can raise discrepencies 
and have them reviewed by the relevant spec authors and implementors and 
get feedback on what the correct behaviour is, and where to raise bugs 
to get non-conforming browsers fixed.
