I'm astonished a professional journalist wouldn't know the connotations of "uppity." Especially given that it was also used about Barack Obama in 2008
But the link is to The New York Times in 2008 - not a British newspaper.
I can see that TV presenter Eamonn Holmes has been blasted for describing Meghan Markle as "uppity" - except that when I clicked on the recording provided by The Sun newspaper he doesn't actually use the word "uppity" - he quite clearly says "uppy attitude." If "uppity" is a specific racial slur in America, then "uppy" would appear to be a completely different word altogether - with a different meaning.Why is everyone reporting that Eamonn Holmes said "uppity" when he said "uppy"?

I also found several other references to "uppity" in connection to the royals.
The Times - May 2016 - so pre MM:
"It’s a tricky proposition, poking fun at the royal family. It’s no longer the mainstream pursuit it once seemed to be.If you were a kid growing up in the 1980s or early 1990s, you could be forgiven for assuming that they were fair game; awkward, distant figures who could not only withstand a ribbing, but who practically demanded one.Spitting Image regularly gave them an absolute beasting and my own Prince Charles impression always attracted a crowd in the playground, provided that there weren’t any double-jointed kids around to steal the limelight."
"Those were more uppity times." "Savaging the royals via exquisitely observed mimicry isn’t something I imagine kids spend much time doing these days"...

The other reference (trouble linking - easy to find if you google) is an article from 1989:
"Fergie dresses like a hillbilly & walks like a duck!"
"UPPITY [their capital letters] fashion expert Mr. Blackwell blasted poor Sarah Ferguson"...
"Despite dumping 45 pounds off her once chubby bod...Sarah Ferguson has been savagely attacked for her lousy taste in clothes and her look. America's feared fashion guru Mr. Blackwell has branded the Duchess of York a "fashion obscenity who walks like a duck with a bad leg." Not stopping there, Mr.Blackwell compares the red-haired royal to a hillbilly when it comes to choosing clothes."She runs around looking as if she makes beds in Ireland or milks cows. She's as badly dressed as anybody I've seen in the backwoods" he said."
Charming!
