Marsilea error in dc.plot_associations()

Describe the bug

Hi, I'm following the tutorial for my own data and I get an error at the dc.plot_associations() step:

TypeError: ColormapRegistry.get_cmap() missing 1 required positional argument: 'cmap'

Is there anything that might have changed in recent marsilea to cause this?

To Reproduce

dc.plot_associations(
    pdata,
    uns_key='pca_anova',  # Summary statistics from the anova tests
    obsm_key='X_pca',  # where the PCs are stored
    stat_col='p_adj',  # Which summary statistic to plot
    obs_annotation_cols = ['Stage', 'CellType'], # which sample annotations to plot
    titles=['Principle component scores', 'Adjusted p-values from ANOVA'],
    figsize=(7, 5),
    n_factors=10,
)
