I dunno that this is something anyone other than easily-irritated old broads think about. It’s definitely a current syndrome: authors writing fiction a good while back didn’t indulge.
But today’s writers, imnsho, do so with impunity. Which is to say, only this e.-i. o. b. (see above) appears to notice.
The characters can read minds: they know what other characters are thinking.
They can also read expressions.
They never fail to get it right.
In fact, novels actually depend upon this amazing ability; and if you refer to anything current – meaning written in your lifetime – you will find it portrayed often.
As most of you know, I don’t read but listen to audiobooks: maybe that’s why I notice.
And maybe that’s why I write in the first person: it’s not just that I’m an egomaniac, but that I cannot read anyone’s mind and have never been able to and am awfully happy with this lack.

Can you give me an example? I’m intrigued by your comment, MR.

I haven’t read (or listened to) any fiction in decades. And very little non-fiction. When your job is reading, editing, nitpicking through hundreds of pages examining type size and font, spelling, punctuation, vocabulary, sentence structure, reasoning, meaning, accuracy of thought and fact, ad nauseum, reading ceases to be fun. To this day I can’t read for pleasure without some part of my brain focusing on spelling, sentence structure, etc., and only because of computers can I read at all without a pencil in my hand.
That mind-reading thing sounds like something an inexperienced author would do.

I have read that publishers prefer first person POV. It brings the readers into the action this giving a better experience.
Yet a lot of Scandi writers right in second person or even omniscient POV – that you alluded to.
I prefer the latter two and find it more difficult to write fiction on 1st. I think that is just my writing style or perhaps my mind??
Writing in 1st feels better for memoir or blogging.
If you write in1st you cannot know what the other character is feeling- just by an expression or gesture.
