When clicking in prettify source while debugging a service worker, the panel showing the content get's in a state that cannot be recovered.

I'm marking prettification bugs as P3 until we decide this feature should get higher priority.

There're 2 problems with this bug + (duplicate) bug 1273730: 1) It's not clear if there's a plan to fix this properly (not by hiding pretty-print button). Some comments in 1273730 say "not fixed YET", but there're no connected bugs, no hints on where to look. 2) "Prettify Source" menuitem is still enabled in context menu, so bug 1273730 wasn't completely fixed

James, can you nuke the menu item as well?

We are hoping to turn on the new debugger in 4 weeks, so all of this is going to be void then. We are already really pressed for time on making that happen, so I'm not sure it's worth spending time on this. We need to figure out what to do with all the current debugger bugs. The new debugger will make it much easier for workers to use sourcemapping/pretty-printing, in fact it might just come for free. The reason is because we do sourcemapping client-side so it's not dependent on the server at all.
