+Subject: [PATCH] combobox: Avoid extra queue_resize()
+
+width-request already ensures it's above the minimum width, so avoid an
+extra queue_resize() when setting size request to (-1, -1).
+
+This is the same way as GtkDropDown works. This also unbreaks
+GtkComboBox after the recent allocation fix in
+75a417e33708dab2bdb2f784a8952e085a12bf03.
+
+Incidentally, this also makes GtkComboBox actually resize its popup as
+intended (that was broken before).
+
+I don't think this is ultimately the final fix, sometimes I still get
+allocation warnings. But the proper fix will probably involve changing
+some more allocation machinery around popovers. This is good enough for
+now.
