rockcraft insists on rebuilding part that has not changed

[nicolasbock]

Bug Description

Using these rockcraft.yaml parts:

    patches:
        plugin: dump
        source: .

    mariadb:
        after:
            - patches
        plugin: cmake
        source: https://github.com/MariaDB/server.git
        source-type: git
        source-tag: mariadb-10.5.28
        build-packages:
            - bison
            - ccache
            - gnutls-dev
            - libncurses5-dev
            - zlib1g-dev

    scripts:
        plugin: dump
        source: https://github.com/MariaDB/mariadb-docker.git
        source-type: git
        override-build: |
            ls -lh 
            install -D --mode 0755 10.5/docker-entrypoint.sh ${CRAFT_PART_INSTALL}/usr/bin/docker-entrypoint.sh
            install -D --mode 0755 10.5/healthcheck.sh ${CRAFT_PART_INSTALL}/usr/bin/healthcheck.sh

When I make any changes to the scripts part, the mariadb part is rebuilt. As far as I can tell, there is no dependency between scripts and mariadb that could invalidate mariadb in this scenario.

To Reproduce

See the rockcraft.yaml snippet.
