Looks like we end up taking this path:

http://searchfox.org/mozilla-central/rev/02a56df6474a97cf84d94bbcfaa126979970905d/widget/gtk/gtk3drawing.cpp#2557

Which stores 0 in thumb_height. Not sure if this is a bug in gecko's expectations or in the gtk glue.
Flags: needinfo?(jwatt)
I'd guess this is a bug in gecko's expectations. The |style| passed through to gtk_style_context_get includes the orientation of the control. I'd guess it leaves/sets the dimension perpendicular to the thumb's direction of travel as/to zero. This code doesn't care about that dimension anyway so we should change the assertion to only assert about the dimension that matters to us.
