Visual Search?

[redlinear]

Two desktops side by side.
On one, I can open any listing, hover my cursor under the "expand" photo in the upper right corner, and see an icon for "visual search". 
I click it and off to the right of the screen I'm seeing mostly the same item from outside of eBay sites. 
WHAT???  I was getting ready to buy this item on eBay, and now I'm directed away from eBay, to Amazon or elsewhere. 

On the other PC, I don't see that icon.  Maybe a different setting?

I think that's a feature of the browser...in Edge browser I see the visual search button when I hover over the photo. That brings up a panel on the right with the image results. I can do it on images on any webpage.  It can also be done with a right click on images. I think it is a new feature on Edge at least I only noticed it recently.

Okay, Yep!  It's the browser.  
Not sure how long this has been there, but, it "might" explain some recent sales issues. 

I was looking into that eBay feature of changing the background to white on listing photo's.
With the reason being "I think there's some reason eBay wants no background...and that reason might have something to do with Search".
Anyway, 
Of the listings that I "visually searched", it seems that if said eBay photo has no background, the Visual Search results all look about the same.  Item on solid white.
If I searched an image with color or texture background?  The results are likewise
