When building the display list for popup frames we hit this early return https://searchfox.org/mozilla-central/rev/08899071a2c8a573ac47ac632869bb92269b3ec3/layout/generic/nsIFrame.cpp#4089 because menupopups are given top layer style here https://searchfox.org/mozilla-central/rev/08899071a2c8a573ac47ac632869bb92269b3ec3/toolkit/content/xul.css#370 The place where top layer items would get added to the display list is https://searchfox.org/mozilla-central/rev/08899071a2c8a573ac47ac632869bb92269b3ec3/layout/generic/ViewportFrame.cpp#163 However that iterates the toplayer list from the document which does not contain menupopups; it contains things like popover, fullscreen, dialog. However, if not culled by that toplayer early return, popups would be culled by this popup specific early return a few lines later https://searchfox.org/mozilla-central/rev/08899071a2c8a573ac47ac632869bb92269b3ec3/layout/generic/nsIFrame.cpp#4110 So I think using a popup check here is the right way to go.
