bors-servo 04271124bb Auto merge of #11695 - asajeffrey:script-thread-dont-panic, r=Ms2ger
Removed some sources of panic from script thread.

<!-- Please describe your changes on the following line: -->
**This PR needs some thought!**

It removes some sources of panic from script_thread.rs, caused by pipeline lookup failure. It's incomplete, as there are some uses of `get_browsing_context` elsewhere in the code.
