[i18n-activity] Use of fillLineGap might cause glyph collisons

steveatkin has just created a new issue for https://github.com/w3c/i18n-activity:

== Use of fillLineGap might cause glyph collisons ==
6.7.6 itts:fillLineGap
https://www.w3.org/TR/ttml-imsc1.0.1/#itts-fillLineGap

It's unclear to me if glyph collisions will occur between the lines. Might we have cases that cause text to become unreadable when a line above contains glyphs that extend below the line that collide with glyphs that extend above a line?
