Text wrapping bug in TextField

we use textfield control extensively in our app. has issue text wrapping causes app go in infinite layout cycle.

this problem occurs because text wrapping algorithm makes textfield height different in each rendering cycle.

this problem not reproducible in ide in debug mode. occurs in installed .air app.

 

steps reproduce:

 

1) make adobe air project , paste code below in main mxml file.

2) generate .air installer

3) install app

4) click in textfield

5) move mouse outside textfield( remain within app).

6) note. textfield textwrapping goes in cycle confused , textfield height differnt in each rendering cycle.
