Log axis and exponent format

Hey all

I have the following plot: https://plot.ly/~zellweger_c/71/
In it, the y-axis is of type ‘log’ and the exponent format is set to ‘e’. As you can see, there are 2 traces: one hovering around ~1000 and the other around 1e-7 and 1e-8.

However, plotly displays the exponent format ‘power’ with the chosen data, no matter what actually has been set as the exponent format. If I disable the trace hovering around ~1000, then the exponent format does indeed change to ‘e’.

Hence, I assume it is a deliberate choice to set it to ‘power’ in certain cases. If so, can you explain the reasoning behind it? Maybe I’m also missing something very obvious?

Can you share the url to the corresponding plot?
