Translate metadata to field content

[Mark Waddingham]

There’s the formattedStyledText property which is like the formattedText but in the form of a style array. If you sum the number of chars in each run up until you find your tag, then you can should be able to use the formattedheight of char 1 up to the summed index to get the vscroll you need.

Warmest Regards,

Mark.
