I have been able to recreate this with a real use client case, as well as s=
ome 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 tex=
t fixes the issue, however still remains when removing the same amount of c=
haracters 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:

te: 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 p=

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 t=

hands the cat to each student. Then, sheallows time for students to color t=
heir picture. Then she passes out a picture of  cupcake, and follows the sa=
me procedure."
