`mplot3.xy` does not respect `ylim` when adding `fit`

[stnava]

example below builds on the documentation code.

this:

  mplot3.xy(x, list(squared = ysq, cubed = ycu), fit = "gam",ylim=c(-20,20))

versus

  mplot3.xy(x, list(squared = ysq, cubed = ycu), ylim=c(-20,20))

would expect limits to be -20, 20 in both cases. not sure if this is intended behavior.
