Me neither.  Weird, as it's very powerful, the key to solving problems 
just like this one, and a great many besides.

I just flagged the omission:

That is odd. As I play with it I'll see if anything else suggests the 
"why" behind that pattern.  Maybe Mark Waddingham can offer some insight 
on that.

I spoke Dr. Peter Brett a couple years back about performance of using 
styledText vs htmlText for tasks where either would be a suitable option.

He reinforced something Mark Waddingham had once written here (or maybe 
it was Trevor?), that the styledText array most closely fits the 
internal structures of field contents.

In contrast, htmlText requires extensive parsing to achieve similar 
results, and usually with much more overhead as expected with such parsing.

In Peter's view, he would be surprised to find any case where parsing 
htmlText would be faster than working with the styledText array.  I have 
no reason to doubt him, and have been using styledText as the basis for 
most things I used to use htmlText for when writing new code.
