+Subject: Bug 1817263 - fix OS picker behavior under Wayland r=ng,jib,stransky
+
+Recent WebRTC backports and changes that are about to be backported from
+upstream to Firefox breaks and will break how we work with PipWire based
+desktop capturer. Currently when constructing device list, a fallback to
+ScreenCapturerX11 is used, as we don't call set_allow_pipewire(), which
+wouldn't make a difference anyway. In such case the only thing we need
+is a placeholder for a screen that will request OS level prompt. We also
+need a way to request both screens and windows in one xdg-desktop-portal
+call as recent WebRTC made each type be called separately, therefore the
+introduction of GenericCapturer. Lastly we need to make sure when there
+is a MediaDevice requesting the OS prompt, that it will be checked as
+first.
+
+In order to use unmodified libwebrtc, Firefox would need to rework the
+OS picker to request each type (screens and windows) separately so we
+can just use regular ScreenCapturer and WindowCapturer. This should be
+done ideally the way Chromium does it, where users can actually see
+even the preview of what they picked over xdg-desktop-portal before it
+is actually shared with requesting web page and they also have option
+to make the request again in case they picked a wrong window or screen.
