Subtle change to Adapting Text

Hi folks,

I posted this comment to the GitHub issue, but I wanted to also share here to perhaps get quick LVTF consensus before any additional discussion Thursday.  What do you think?

"I'd like to suggest new compromised wording to address the following concerns:

PS - I also commented about where MathML content fits in here.  Some styles are not applicable (e.g. font or word-spacing), but others are important (e.g. color).  Any thoughts there would also be appreciated.  Thanks.
