Description BJ Burg 2020-09-29 16:29:32 PDT
This is only used to deserialize objects, there is no point to allowing inspection.

There is some concern that setting the property will happen too late and this will already be paused underneath -[JSContext initWithVirtualMachine:].

Alternate ideas:
- temporarily disable automatic inspection when initializing that JSContext.
- add SPI to JSContext to specifically disable automatic inspection.
- in the pauseWaitingForAutomaticInspection wait loop, check if remote inspection has been disabled and bail if so.
- make webinspectord detect when an automatic inspection candidate has disabled remote inspection and delete any associated automatic inspection sessions.

Oof, looks like we should be doing this instead:

previous = JSRemoteInspectorGetInspectionEnabledByDefault()
// initialize the JSContext, disable remote inspection explicitly.
