I'm trying to use 2 remote parts simultaneously in this simplified YAML: name: dual-remote-parts-bug version: 0.1 summary: Bug description: Bug confinement: strict grade: devel apps:   dual-remote-parts-bug:     command: ls $SNAP/lib parts:   bug:     plugin: nil     after: [desktop-gtk2, xwayland-kiosk-helper] The second remote part "xwayland-kiosk-helper" is defined here: https://github.com/gerboland/xwayland-kiosk-helper/ It creates a file lib/libxwayland-preload.so which I see is created in the "stage" directory, but it is not copied into the "prime" directory for some reason. But the bin/xwayland-kiosk-launch file is copied?! There is no "prime" specification in the remote snap, so shouldn't everything that is staged be copied into the prime?
