Carol Frampton commented on FLEX-33295:
---------------------------------------
In that case Alex is right. This is a well-known problem and you'll find
several existing issues in the bug base for similar cases. I ran your test
program and didn't see scroll bars so I assumed it was a different issue.

> I have been able to recreate this with a real use client case, as well as
> some lorem ipsum text of the same length(but not every time since the lorem
> ipsum text is randomly generated). Removing the first two words in the text
> fixes the issue, however still remains when removing the same amount of
> characters at the end of the text instead. This leads me to believe this is
> a random text wrapping issue.
> We tried testing on a mac and everything ran as expected, it appears to be a
> windows only issue.
> Here is some simple code to reproduce the issue:

> testText = "The learning tasks and activities
> are aligned with the instructional outcomes and are designed to challenge
> student thinking, resulting in active intellectual engagement by students and
> teacher scaffolding. The pacing of the lesson is appropriate providing most
> students the time needed to be intellectually engaged.Ms. Pruden begins the
> math and Reading lesson by strategically placing her chair between two rows
> of desks and methodically assisting one student then another. She first
> assists a student to her left (Artice) on simple addition, such as 1 + 4 = 5;
> then she turns to her right to work with another student (Fode) on reading
> the numbers of his address. She methodically moves her chair down the middle
> of the two rows to work with the other remaining students. One student
> (Dexter) works independently on a calendar; he places the word 'cloudy' on
> today's date: October 25. He is getting his assignments from his individual
> basket of daily tasks. Ms. Pruden then worked with Aujana who isworking on a
> ruber puzzle of the alphabet. She asks her t repeat after her as she points
> to each letter and names each letter of the alphabet. Ms. Pruden worked back
> and forth with Fode, Artice and Auana. Ms. Gordon, her teacher assistant,
> worked with Dejuan as he counts dots that are pasted on a paper dinosaur.
> After 45 minutes, Ms. Pruden stops and directs all of the students to join
> her at the semi-circle table to work on consonant sound for the letter 'C.'
> The teacher passes out a picture of a cat, and emphasizes the 'KK' sound as
> she hands the cat to each student. Then, sheallows time for students to color
> their picture. Then she passes out a picture of cupcake, and follows the
> same procedure."
