Web Inspector: console should allow JS execution in the context of an isolated world

[Yury Semikhatsky]

Let's make it possible to use the console to execute JavaScript in the context of a content script embedded in the page. 

This is an upstream for Chromium issue: http://code.google.com/p/chromium/issues/detail?id=95865

Can this happen?

Chrome(i)um does not compile without inspector.

What does it mean?

EvaluationContext ?

I would rename it to "contextId" or type "ContextId".

reorder by importance?

Each content script lives in an isolated context and this parameter may be used to specify on of those contexts. If the parameter is omitted or 0 the evaluation will be performed in the context of the inspected page.", "hidden": true },

I think it is better to combine the frame and context id into the single contextId and stick to that term in runtime / debugger.

It is a list of domains for which we don't generate register<Domain>Dispatcher() methods in the front-end.

Renamed to ExecutionContextDescription, introduced ExecutionContextId.
