The option is correctly set, you can see the output of gsettings in the attached video. Regardless, the issue seems to have spontaneously resolved itself despite no apparent change to the installed version of dash-to-dock (apt list still has it at 72~ubuntu5.22.04.1), so I've marked this bug as Invalid. Thanks for your help.
