It appears I may have created some confusion by actioning the discussion we had about moving the regular weekly meeting later by one hour – I have just begun the meeting… and just two of us are on it right now.

Focus topic for this week
Please prepare your thoughts for discussion of what background-on-span-affecting semantics should be supported in TTML2, covering at least the issues:
Should background of a span be height of text in line or computed lineHeight? #101<https://github.com/w3c/ttml2/issues/101>
Ways to make span background height be lineHeight #150<https://github.com/w3c/ttml2/issues/150>
Clarify semantics of content bpd for inline and line areas #163<https://github.com/w3c/ttml2/issues/163>
Add support for adjacent background area merging #189<https://github.com/w3c/ttml2/issues/189>
This is in the context also of how we resolve the recently discussed IMSC 1.1 issue: Control background between adjacent lines <https://github.com/w3c/imsc/issues/195>
