Using a RichTextCtrl with Margins and a very specific qtf causes the size calculations to ignore a word that is moved from one line to the other.

Application attached. Press the button.

Here is the interesting bit.

The QTF ends in "}}]". This causes the problem.

Using "}}\n]" still has the problem.

Using a space, "}} ]" works.

Is this a bug or did I misunderstand spacing rules in QTF?

Edit: adding the space, "}} ]" causes other qtfs that displayed properly before to be larger.

This can be reproduced by deleting "descending" from the qtf.
