Missing render blocking mark for resource


I see that one css is still render-blocking but the mark on the test doesn’t show and the resource has a non-render-blocking label in detail.

It’s not true, cause when block this resource I see that Start Render is faster then with that CSS.

I guess it’s cause by preload before stylesheet:

I know that this preload in this place is meaningless, but the test should mark this resource as render-blocking.
