* Source/WebKit/UIProcess/Extensions/Cocoa/API/WebExtensionContextAPIDeclarativeNetRequestCocoa.mm:
(WebKit::WebExtensionContext::declarativeNetRequestUpdateDynamicRules): Filter out any rule IDs that don't match, and make sure
adding any rules doesn't take us over the limit.
(WebKit::WebExtensionContext::declarativeNetRequestUpdateSessionRules): Ditto.
* Source/WebKit/UIProcess/Extensions/Cocoa/WebExtensionContextCocoa.mm:
(WebKit::WebExtensionContext::loadDeclarativeNetRequestRules): Keep track of the session and dynamic rule IDs that have been loaded.
