CSS styles access

[Mayhew]

I am interested in accessing CSS styles rules via something like InspectorCSSAgent::getMatchedStylesForNode() from chromium\src\third_party\WebKit\Source\WebCore\inspector\InspectorCSSAgent.cpp from my CEF3 app. Basically I would like to be able to access data that seems to only exist deep in webkit. It appears that there is not currently a way to access things at that level via CEF's current DOM access methods. The purpose is to augment the somewhat limited capabilities of the Javascript getMatchedCSSRules method for pages hosted in my CEF browser.

Is there a way to achieve what I am looking to do?

You could call getMatchedStylesForNode via the DevTools remote debugging protocol, but that's probably not what you're looking for. Anything else would involve C++ changes to CEF/Chromium/Blink.
