My emoji in Google Hangouts flip-flops on my MacBook, why? 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:

"my old emoji"  (Google?)

"my new emoji"  (Apple?)
Both emojis are Google's, they have nothing to do with Apple's emojis.

Many people didn't like Google's "blob" emojis, so Google changed it to this new one.
