pkgdev bugs sometimes ignores stabilization groups

I don't really understand when or why. But see e.g. https://bugs.gentoo.org/949056#c7 Also, based on what happened in https://bugs.gentoo.org/959075 I tried to create another one! ``` $ cat metadata/stabilization-groups/gnome/gtk-doc.group dev-build/gtk-doc-am dev-util/gtk-doc $ pkgdev bugs -s =dev-build/gtk-doc-am-1.34.0 --edit-graph --stabletime=1 Checking =dev-build/gtk-doc-am-1.34.0 on 'amd64 arm arm64 hppa ppc ppc64 sparc x86' Merging @gnome/gtk-doc group nodes: (=dev-build/gtk-doc-am-1.34.0,) $ pkgdev bugs -s =dev-util/gtk-doc-1.34.0-r1 --edit-graph --stabletime=1 Checking =dev-util/gtk-doc-1.34.0-r1 on 'amd64 arm arm64 hppa ppc ppc64 sparc x86' Checking =dev-build/gtk-doc-am-1.34.0 on 'amd64 arm arm64 hppa ppc ppc64 sparc x86' [added for =dev-util/gtk-doc-1.34.0-r1] Merging @gnome/gtk-doc group nodes: (=dev-util/gtk-doc-1.34.0-r1, =dev-build/gtk-doc-am-1.34.0) ``` Works for one, not the other? But! Both times it says "Merging @gnome/gtk-doc group nodes", so it clearly knows what it should be going for... The alsa thing is the same: ``` $ pkgdev bugs -s =alsa-ucm-conf-1.2.14 --edit-graph Checking =media-libs/alsa-ucm-conf-1.2.14 on 'amd64 arm arm64 hppa ppc ppc64 sparc x86' Merging @alsa group nodes: (=media-libs/alsa-ucm-conf-1.2.14,) ```
