1767941 - Once `navigator.clipboard.readText()` has been enabled behind a pref, check behavior when the "Paste" button overlaps another context menu

Status: NEW

(Core :: DOM: Copy & Paste and Drag & Drop, task)

Description

[Mirko Brodesser (:mbrodesser-Igalia)]

Potentially problematic case: when opening the right-click context menu via a right-click and opening the "Paste" popup in the corresponding "mousedown" event handler.

Implement forbidding pasting when the user activation stems from a context menu (e.g. Right click), because it the "Paste" button could overlap with that menu.
