Package: r-cran-plotly Version: 4.10.4+dfsg-2 Severity: serious
r-cran-plotly test-Depends (and runtime Recommends) r-cran-dendextend, which is not in testing.
Because of this, it's migration-reference autopkgtests are failing as uninstallable, which is RC by https://release.debian.org/testing/rc_policy.txt.
(The non-migration-reference runs are "passing" because of a known issue in autopkgtest that allows them to take more packages than requested from unstable: https://sources.debian.org/src/autopkgtest/5.49/runner/autopkgtest.1/#L292 and #1084880. i.e. r-base 4.5 won't actually help.)
The obvious fix is to remove that test-Depends and accept the reduced test coverage for trixie.
(riscv64 is also failing because sprintf doesn't support %02d formats there: since this is a crash not a wrong result, I suggest ignoring it.)
