Standalone media documents use a <video> element to play all media. In the case of audio, this should not use the default intrinsic height of 150. This came up as a bug report from someone who was opening audio files in popup windows that were 100px high, and thus the controls were not visible. By setting the intrinsic height for all media on standalone documents to 0 (actually 1, see patch comments) everything works ok. Video gets resized to its native dimensions when the video loads. <rdar://problem/6458142> REGRESSION: Audio files have misplaced control bars (20687)
