Autoscaling graphs - hidden traces with error bars

Could not find a similar issue, so I will query here as to whether this is a bug, or whether I am misunderstanding how hidden traces work.

When hiding a trace on a normal graph, there is the option to either have the axes autoscale to just the visible traces with 

or alternately to autoscale the axes even including the hidden trace, ie 

However, this doesn't work if the waveRef in question has error bars included. If the hidden trace has an errorbar added, ie

then the behaviour of the plot is as if the trace was included in the autoscale (ie hidetrace=2, even if 1 is specified).

Is this the desired behaviour of the hidetrace option?
