Closed Captions are playing when Subtitles are set to "None"

Has something changed?

While playing an MKV file that has Closed Captions (CC) embedded they are being played even though they are deselected in “Subtitles” in Playback Settings.

There doesn’t appear to be a way to turn them off. I have resorted to removing them using this command but that seems burdensome.

ffmpeg -i input.file -codec copy -bsf:v "filter_units=remove_types=6" output.file

IIRC that type of close captions isn’t usually detected as an actual subtitle but embedded into the video stream. FFMPEG can remove it (as per your example).
