Problem is that there is unwanted and unremovable popup has been added.
When I press the "Copy link" button there is only one thing thing can happen - the link is being copied. Nothing other can happen.
There is no "fail" scenario to link to be not copied.
There is no "happened something else" scenario - only link can be copied. Nothing else but placing the link into the clipboard can happen.
There is only way of situation development after pressing "Copy" button and there is absolutely no sense to show the succession of this explicitly.
what if something important is removed by mistake?
Em, what? I think I misunderstanding you in some way... How anything anywhere can be removed by copying of piece of text?
