Reviewed by Alan Baradlay.

When resolving computed style in a non-rendered subtree we fail to take container queries into account.

(WebCore::Document::styleForElementIgnoringPendingStylesheets):

Take care to have updated document style if it is not clean and we are resolving the root element.

* Source/WebCore/dom/Element.cpp:
(WebCore::Element::resolveComputedStyle):

- Ensure the style scope is flushed so stylesheet data is current.
- Don't bail out when encountering display:none subtree, the ancestors may still affect its style.
- Fall back to a full style update if we encounter a query container with invalid style in the ancestor chain.
