Failing to open trading UI

Video describes it all. In the video clip what I did to the villager was spamming right click and it simply failed to open his UI

The villager comes from a cured zombie villager, and its condition was just about normal as an average farmer villager. The villager has a valid jobsite, and slightly different from the case in MC-154201

P.S. I had enabled Programmer art into my Minecraft

*EDIT: I later realized the villager needed a job site to open, or else it'll shut instantly
