Hi Webkit-Dev, I'd like to request an official position from webkit on the document-access <https://github.com/dtapuska/documentaccess> proposal. This proposal allows a frame tree to give up the requirement that same-origin frames might be in the same event loop via an attribute. TAG discussion was here: https://github.com/w3ctag/design-reviews/issues/397 Chromium Intent to Ship: https://groups.google.com/a/chromium.org/d/msg/blink-dev/TzuPAx9ZOk0/HYOf3FF... dave.
