1076912 - [highlighter] Pick pseudo-elements from the page with the mouse

Status: RESOLVED DUPLICATE of bug 920142

(DevTools :: Inspector, defect)

Description

[Patrick Brosset <:pbro>]

bug 920141 adds support for ::before and ::after in the inspector markup-view, which is nice.
It would be even nicer if we could pick pseudo-elements directly with the mouse, when using the inspector's picker.

The element picker works by adding a mousemove event listener on the page. When pseudo-elements get hovered, the listener callback gets executed but the target is the element itself, not the children pseudo-element.

I guess one way to achieve this would be to check if the element has pseudo elements, and if yes, check if the mouse coordinates matches with their boxquads.

It might be slow, but worth investigating.

Sounds identical to Nicks bug 920142.
