What is supposed to be copies from the context menu of a plot and where can it be pasted?
I don’t know what is actually implemented, I’ve barely used VSCode but from similar applications what I would expect/hope for is this:
Is dependant on the application where you paste, following a priority list of mime types. If you paste in Inkscape it’s a vector image. If you paste in Word it’s a png. If you paste in Paint it’s a bitmap and if you paste in Notepad it’s a textual summary.
That context menu doesn’t have any functionality. It only exists because no one spend time figuring out how to remove it.
