Error when setting aspect to 'auto'

[maximlt]

Recording an issue we found when documenting aspect. Very likely a HoloViews issue but I wanted to record it here first before I forget.

import hvplot.pandas
import hvsampledata

df = hvsampledata.penguins("pandas")

plot = df.hvplot.scatter("bill_length_mm", "bill_depth_mm", aspect="auto")
hvplot.render(plot)

TypeError: '>' not supported between instances of 'str' and 'int'
