My javascript file is displayed as a single line of text in the chrome debugger. Why?

Question

I seem to run into this randomly. It usually displays the file normally, but sometimes it's all scrunched onto one line. I can't figure out what's causing it.

Answer 1

N.B.: In the current version of Chrome, this is actually done by clicking on the {} icon ("pretty print") on the lower left of the developer tools pane.
