ladybird/Libraries/LibWebView/WebContentClient.h
Timothy Flynn daca9f5995 LibDevTools+LibWebView+WebContent: Selectively fetch DOM node properties 
When we inspect a DOM node, we currently serialize many properties for
that node, including its layout, computed style, used fonts, etc. Now
that we aren't piggy-backing on the Inspector interface, we can instead
only serialize the specific information required by DevTools.
