Box Plot - hover info of fences


Can anyone shed any light on how Plotly decides which information to show on hover with a box plot?

I have shown my example below.

Sometimes the lower the lower fence is identified as “lower fence” and in other cases it will show “minimum”, and analogously with “upper fence”/ “max”.

I know the lower fence is determined by finding the last sample point below Q1 - 1.5 x IQR; I’m thinking maybe “lower fence” is used if this last sample point is not the minimum of the data set, and “min” used when it is. Can anyone confirm this?
