A few days after I asked my (now closed) question Is region-specific blocking built-in to MacOS more extensive than a few emoji? the emoji shown in Google Hangouts in the Chrome browser on my MacBook Air flipped from "my original emoji" to "my new emoji".
Then a few days ago, it flipped back to original in Hangous, for a few minutes, then flipped back again to "my new emoji".
I don't really know where emoji "live" or how they get into Hangouts, but I especially don't understand how it could flip-fpop back and forth like this.
Is there a way I can stabilize this on my computer? Is this a decision made in my OS or in Chrome? Can I somehow set Hangouts it to "my old emoji" permanently?
Here is one example of the two emoji sets:
