Thai words are not wrapped correctly

[mobilebilly]

I cannot read Thai, but I realized Thai text are not being wrapped correctly in some cases.
In contrast, the Thai text are displayed correctly under webkit browsers (Tested with Chrome 26.0.1410.64 m)

e.g. http://www.greengardenbars.com/

The issue can be reproduced in phantomjs 1.9

Due to our very limited maintenance capacity, we need to prioritize our development focus on other tasks. Therefore, this issue will be automatically closed (see #15395 for more details). In the future, if we see the need to attend to this issue again, then it will be reopened. Thank you for your contribution!
