Description
Currently, the layer() function does not initialize all parameters for the associated Geom or Stat. This can lead to issues when multiple parameters share a common prefix. A typical example is StatSummary, which includes parameters like fun, fun.data, fun.max, and fun.min. If a Stat is invoked within a geom_* function using the stat argument, problems can arise in StatSummary$setup_params where params$fun may be incorrectly matched to fun.data, fun.max, or fun.min due to R's partial matching behavior.
Please see the warning message.

fill = c(rep("A", 4), rep("B", 4))
