This issue seems to have returned?

I have an entity where I use HA's UI to set its precision to two decimals, as it represents a monetary value:

You can see the entity card respecting this setting, but not the mushroom template card:

Additionally, the mushroom template card also doesn't respect the locale for the decimal separator (expecting "," in my context, not "."). Will file separately for this.

Running HA 2023.12 and Mushroom 3.2.2.
