Who owns(stores ?) my document in chromium ?
Raw
WhoStoresMyDocument.md

I was getting interest in looking for 'WHERE document() comes from?'.

'Chromium' is quite big and complicated open-source project, so even traversing source code for looking 'where it comes from' also hard. However, it was statred from HTMLMediaElement class(chromium/src/third_party/WebKit/Source/core/html/HTMLMediaElement.cpp). And, finally real implementaion of document() belongs to a class TreeScope(third_party/WebKit/Source/core/dom/TreeScope.h).

The inheritance seems like below, shortly. HTMLMediaElement - HTMLElement - Element - ContainerNode - Node and, Node has TreeScope and it has 'Document& document() const'.

I hope, someone (including me) needs this quick information.
