[Domain Mapping] Domain Mapping 4.4.3.1 Breaks front end https redirect

This issue only showed up as of 4.4.3.1, but I've confirmed it on two different installations.
I have the setting selected:
Would you like to force http/https in front-end pages: "Force https"
However, pages are not being redirected to https and are still accessible via http.
I've rolled back my installation to 4.4.3 and the problem is resolved.
