Antti,

Does WebKit do this whether the plug-in handling the format is QuickTime,
Windows Media/Silverlight, Flash, etc.?

If users do show the <video> element's controls, are the plug-in's native
controls shown?  And when that happens, does the <video> element's height
attribute then change if though the video's actual height hasn't changed?

If that's the case, is the expectation that authors will need to temporarily
hide controls (or make sure they're already hidden) before getting its
height?
