r=me, nice catch!

> Source/WebCore/ChangeLog:15
> +         Previously, the conversion for the mock capture value was implicit from a bool pointer to an optional.
> +         Make an explicit conversion as done for regular settings.

Style: there seems to be an extra space before each of these lines.

> Source/WebCore/inspector/agents/InspectorPageAgent.cpp:429
> +    return *value;

Style: I prefer using `.value()` with `WTF::Optional` so it's a bit clearer that it's not a pointer.

> Source/WebCore/inspector/agents/InspectorPageAgent.cpp:445
> +    auto overrideValue = toOptionalBool(value);

NIT: Web Inspector typically uses `as*` instead of `to*` for it's type conversions (see `asBool` in InspectorRuntimeAgent.cpp).

> Source/WebCore/inspector/agents/InspectorPageAgent.cpp:448
> +    case Inspector::Protocol::Page::Setting::name: {                            \

NIT: we can remove the `{` and `}` and make this slightly simpler.

Done.

I like using pointer-like code, for instance "if(value) value->doSomething()" or "if(value) doSomething(*value)".
The one case I am sometimes using .value() is when moving the value.
"if (value) doSomething(WTFMove(*value))" seems a bit strange.
