In case one disabled inheritable property on container, subsequent inspection of the node is not providing results.
Created attachment 55870 [details] [PATCH] Proposed change. Inherited styles disabling is still not working as I'd like it to: in case inherited property is disabled, it won't show up in inherited list at all. But at least it is not failing for subsequent selections anymore + i added some styles mutation tests.
