Trace hover label color

How can we change the trace background color on the hover text? Changing the hover label background color only updates the data field and not the trace field. We have a dark theme plot and the trace names are sometimes hard to read. Below is an example.

We are using custom colored traces but the labels are still hard to read when using the default colors.

We don’t expose a way to do that at the moment. Though, it would make a nice addition to the library.
