Mannequins' name tags are visible when on a team and ridden

Steps to reproduce:

team add test
summon mannequin ~ ~ ~ {Passengers:[{id:"minecraft:armor_stand",Small:1b,Invisible:1b,Marker:1b,CustomName:"test",CustomNameVisible:1b}],Team:"test"}

Expected behaviour:

Because the mannequin has a passenger, the name should be hidden as is the case if it is not on a team

Observed behaviour:

Both the mannequin and the passenger’s names are visible
