`Anova.mmrm` incompatibility with `broom::tidy()`

**Summary** Thank you for the `car::Anova()` method for `mmrm` models! We discovered a potential compatibility issue with this output and `broom::tidy()` that was surfaced via `cardx::ard_car_anova()`. It seems that the naming conventions used in the `Anova.mmrm()` method are not recognized by `broom::tidy()`: ```r fit <- mmrm::mmrm( formula = FEV1 ~ RACE + SEX + ARMCD * AVISIT + us(AVISIT | USUBJID), data = mmrm::fev_data ) car::Anova(fit) |> broom::tidy() ``` results in: ``` mmrm() registered as car::Anova extension # A tibble: 5 × 5 term Num.Df Denom.Df F.Statistic Pr...F. <chr> <dbl> <dbl> <dbl> <dbl> 1 RACE 2 166. 36.9 5.54e-14 2 SEX 1 166. 0.376 5.41e- 1 3 ARMCD 1 169. 31.4 8.30e- 8 4 AVISIT 3 149. 143. 1.39e-43 5 ARMCD:AVISIT 3 148. 0.258 8.55e- 1 Warning message: The column names Num.Df, Denom.Df, F.Statistic, and Pr...F. in ANOVA output were not recognized or transformed. ``` I'm not sure if this issue belongs here or the `broom` package - please let me know if it should be the latter. Thanks for your consideration! **R session info** <!-- Paste verbatim output from `R -e "utils::sessionInfo()"` below. --> ```sh R version 4.4.1 (2024-06-14 ucrt) Platform: x86_64-w64-mingw32/x64 Running under: Windows 11 x64 (build 26100) Matrix products: default locale: [1] LC_COLLATE=English_United States.utf8 [2] LC_CTYPE=English_United States.utf8 [3] LC_MONETARY=English_United States.utf8 [4] LC_NUMERIC=C [5] LC_TIME=English_United States.utf8 time zone: America/New_York tzcode source: internal attached base packages: [1] stats graphics grDevices utils datasets methods [7] base loaded via a namespace (and not attached): [1] vctrs_0.6.5 nlme_3.1-164 cli_3.6.3 [4] rlang_1.1.4 Formula_1.2-5 stringi_1.8.4 [7] purrr_1.1.0 car_3.1-3 generics_0.1.3 [10] glue_1.8.0 backports_1.5.0 TMB_1.9.16 [13] fansi_1.0.6 grid_4.4.1 abind_1.4-8 [16] carData_3.0-5 tibble_3.2.1 lifecycle_1.0.4 [19] stringr_1.5.2 compiler_4.4.1 dplyr_1.1.4 [22] Rcpp_1.0.13 pkgconfig_2.0.3 tidyr_1.3.1 [25] rstudioapi_0.16.0 lattice_0.22-6 mmrm_0.3.15 [28] R6_2.5.1 tidyselect_1.2.1 utf8_1.2.4 [31] pillar_1.9.0 Rdpack_2.6.2 rbibutils_2.3 [34] magrittr_2.0.3 checkmate_2.3.2 Matrix_1.7-0 [37] tools_4.4.1 broom_1.0.10 ```
