The description of hostbits and xbits in the latest document does not match the status quo.
https://suricata.readthedocs.io/en/latest/rules/xbits.html#xbits-keyword

alert ip any any -> any any (msg:"test xbits set fakehost"; xbits:set, fakehost, track ip_dst; sid:1;)
alert ip any any -> any any (msg:"test xbits isset set fakehost and set fakerservice"; xbits:isset, fakehost, track ip_dst; xbits:set, fakeservice, track ip_dst; sid:2;)
alert ip any any -> any any (msg:"test xbits isset set fakeservice"; xbits:isset, fakeservice, track ip_dst; sid:3;)
I can't get an alert triggered by the third rule.
