Why does Arabic text sometimes break into two lines?

Question

Here's how it should be (Firefox):

I have no idea why this is happening. I think this is solvable with help overflow, but I would like to know the reason, if possible.

Update: It seems that the problem is related to word-wrap: break-word;in my css. Removing this line solved the problem. I'm still curious to know the reason.
