You might need to clarify the video a bit more, in terms of what you're doing specifically and what you expect.
On mobile devices, when content overlays are opened (like this or a popup menu), we add another element to cover the page behind it in order to prevent clicks being processed unexpectedly when tapping to close this menu. Given that the menu is open and I presume you're long pressing, this is more or less expected. If you just tap, it should hide the menu/member card.
