[LH3049] : Selection highlighting and cursor have incorrect offset in Scriptwriting mode

-open interactive tutorial
-create empty document
-switch to scriptwriting mode
-type something
-select it

-> The cursor (on my Windows, scaling is 225% or 250% I think) is at the bottom of the text. Also the selection highlight appears way too low from the actual text.

There was a mention of selection not working correctly with PDF selection, but nothing about scriptwriting in normal documents.

Windows 10, spring update

It seems also highlighting produced automatically by commenting is also incorrectly rendered (has incorrect vertical offset, appears way too high)

Thanks. This has been filed.
