status_middle_separator color can not be set, appears black/default

[mrt181]

I am not requesting help with my configuration and believe something is genuinely broken.

• Something is really actually broken.

Is there an existing issue outlining your problem?

• I have searched the existing issues and they do not solve my problem.

Describe your problem.

I am setting a middle separator to get a slanted status line.

but its color does not blend with the surrounding settings and I can't define a color for the separator.

Paste your configuration.

Where is the middle bg option documented? Because it doesn't exist.

Also this is not a bug, this is a support question. Closing

You can set the middle separator trivially to anything with embedded styles
