Source of mpv: local build of master at e5d85704a3bbf4766ad64133b07d7c3a27f732ac
Introduced in version: Unknown

Reproduction Steps

Run:

mpv --no-config -help=watch-later-options

And inspect the default value shown in the output

Expected Behavior

I was expecting the default value for watch-later-options to contain the corresponding secondary subtitle options (when they exist) for any primary subtitle options in the default value.

Actual Behavior

Running this command in Terminal on a Mac:

mpv --no-config -help=watch-later-options | grep 'default:' | sed 's/.*(default: //; s/).*//' | sed -e $'s/,/\\\n/g' | sort

Provides an easy to read list of the options contained in the default value for watch-later-options:

watch-later-options default:

The following secondary subtitle options are present:

secondary-sub-ass-override
secondary-sub-pos
secondary-sub-visibility

But secondary-sub-delay and secondary-sid are missing.
