The popup doesn't display at the right place.

I think the popup test here should be changed.

The popup doesn't display at the right place.

• The component popup is never made to work with containers that have Y scrolling.
• As it detect the mouse position on the window, but if we then set the popup at that mouse position it'll be incorrect as we have to take the window.srollY (the amount of scroling done in pixels) into the account.
• Even if we take the window scrollY into the account for e.g popup.show(x, y + window.scrollY)
  • The line here adjust for out of screen will try to adjust the popup (as we're passing y + window.scrollY ), which is not needed as the actual y is still within the screen.

The Fix is

• Use position: absolute for a popup which is positioning itself relative to an element of height 100vh. Just shown in above commit here (you could also add position: relative on it, but not necessary here).
