Looks good but a few questions.

> Source/WebCore/inspector/agents/InspectorPageAgent.cpp:337
> +    m_page.enableICECandidateFiltering();

I don't think this is what we want. Shouldn't we be removing some kind of ICECandidateFiltering override? This seems to always enable it again when Web Inspector closes.

> Source/WebInspectorUI/UserInterface/Base/Main.js:2172
> +    if (PageAgent.Setting.ImagesEnabled || PageAgent.Setting.AuthorAndUserStylesEnabled || PageAgent.Setting.ScriptEnabled || PageAgent.Setting.NeedsSiteSpecificQuirks || PageAgent.Setting.WebSecurityEnabled) {

I don't think you need to check all of these. And maybe if you do they should be `InspectorBackend.domains.Page.Setting` checks instead of `PageAgent.Setting` checks.

> Source/WebKit/Shared/WebPreferencesDefaultValues.h:-119
> -#define DEFAULT_MOCK_CAPTURE_DEVICES_ENABLED true
>  #else
>  #define DEFAULT_ACCELERATED_DRAWING_ENABLED true
>  #define DEFAULT_CANVAS_USES_ACCELERATED_DRAWING true
> -#define DEFAULT_MOCK_CAPTURE_DEVICES_ENABLED false

Why are we changing this default value in this patch?

The weird thing with this setting is that it only seemed to be called during the creation of a `WebPage`, and only ever to turn it off.  Changing the preference didn't seem to have any effect for existing pages.  I'll rework it with a setting (and see if I can write a test for it ).

I noticed that the underlying `DeprecatedGlobalSettings` didn't follow this same pattern, so I figured it should match.  I'll change this back.

(In reply to Truitt Savell from comment #22)
I skipped the test on WK1, as it appears that `MEDIA_STREAM` isn't yet supported on WK1 .

inspector/page/overrideSetting-ICECandidateFilteringEnabled.html is also a flakey timeout on Mojave WK1
