I think this one is actually caused by platform code. Around http://searchfox.org/mozilla-central/rev/3a3af33f513071ea829debdfbc628caebcdf6996/layout/xul/nsXULPopupManager.cpp#778 all the nsXULPopupManager::ShowPopup* methods call GetPopupFrameForContent with true as the aShouldFlush parameter. We also hit this with a different stack when opening the awesomebar panel: "openPopup@chrome://global/content/bindings/popup.xml:66:15", "_openAutocompletePopup@chrome://browser/content/urlbarBindings.xml:1889:11", "openAutocompletePopup@chrome://browser/content/urlbarBindings.xml:1803:11", "openPopup@chrome://global/content/bindings/autocomplete.xml:393:13", "set_popupOpen@chrome://global/content/bindings/autocomplete.xml:103:10", "notifyResults@file:///<appdir>/components/UnifiedComplete.js:2193:5",
I cannot reproduce this one anymore.
