1759528 - Going back to an SHEntry should clear its wireframe

Status: RESOLVED DUPLICATE of bug 1766305

(Core :: DOM: Navigation, defect)

Description

[Mike Conley (:mconley) (:⚙️)]

This was discovered while writing tests for the SHEntry wireframe capturing behaviour in bug 1749575. The tests are currently marked "todo" so that they can land in advance of fixing this.

Essentially, when doing a history back navigation to an SHEntry, it is expected that we clear the wireframe for it. Essentially, anytime an entry is loaded, its wireframe should be cleared. It's only upon transitioning away from an entry that a wireframe should get captured and stored.

What is a wireframe? ;)
Document.webidl could use some comments.

Hey, sorry for the lack of context here.

A wireframe is a low-fidelity representation of a document. It's effectively a collection of rects and colours ordered back to front. I've attached a screenshot of a wireframe for the Facebook login page as an example.

We're currently experimenting with wireframes as a way of representing history without having to keep screenshots of sites around.

My patch in bug 1766305 fixes the todos in the test.
