[webvtt] Wide Review Comment 2017: Use of lines as positioning constructs

nigelmegitt has just created a new issue for https://github.com/w3c/webvtt:

== Wide Review Comment 2017: Use of lines as positioning constructs ==
Copy/paste from https://lists.w3.org/Archives/Public/public-tt/2017Sep/0080.html - raising as an issue for tracking/disposition purposes.

It is not clear how the use of lines as a positioning construct is defined. Whereas section 4.4 "line cue setting" says that the height of a line is based on the first line, in ยง6.1, step 12.1 bullet two, the line height is initialised to a very specific value 5.33vh, regardless of the height of the line, and I can't see anywhere that sets another value in its place (I could not see any reference to the line-height property in the rendering section, but please point me to it if it is there). 

#371 is related.
