            Bug ID: 24037
           Summary: [WebVTT]
           Product: TextTracks CG
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: WebVTT

When adjusting the position of cue boxes, if a cue's text track cue
snap-to-lines flag is not set, step 2 says 

"Position the boxes in boxes such that the point x% along the width of the
bounding box of the boxes in boxes is x% of the way across the width of the
video's rendering area, and the point y% along the height of the bounding box
of the boxes in boxes is y% of the way across the height of the video's
rendering area, while maintaining the relative positions of the boxes in boxes
to each other."

I thought the line alignment and position alignment would be used to determine
which point in the cue box is specified by the positions, rather than using the
line and position values as the anchor points. Is the spec just lagging behind
here?

The alignment values are used above in step 7 when computing the x-position and
y-position. However, when we get to the step of adjusting the boxes, these
values appear to be discarded and we use the algorithm described above.
