Why does the transparent background turn black when pasting an image from the clipboard into Photoshop?

Question

Adobe Photoshop

Good afternoon, why does the transparent background turn black when pasting a picture from the clipboard into Photoshop?

But if you save the image to your desktop and open it in Photoshop, then the transparent background remains transparent.

Initially, I thought the problem lies in the color profile, but after sorting through the n-th number of profiles, this did not give any results.
I googled, found a couple of forums, but did not find any clear answers.

Answer 1

Ancient problem. All my life I have to save PNG first, and then open it in Photoshop.
But you can make life a little easier, for example, here https://addons.mozilla.org/en-US/firefox/addon/ope... for chrome, there seems to be one too.

Answer 2

probably only information from the R, G and B channels is copied to the buffer, ignoring the alpha channel (transparency).
Correct answer: the image should be saved, not copied.

Answer 3

In earlier versions of PS, this was not observed, for the simple reason that it was allowed to open files directly via the http protocol ( http://[image_address.png]), now this convenient function has been cut out. And the only way out is to save somewhere, open again - everything is for your "convenience".
