I have seen this issue on several forums for Photoshop CC but nothing for Elements 2021. I am used to using the old Photoshop CS5.5 where I could see the bounding box as the image overlapped the main window. With Elements, the bounding box with handles shows only inside the active window. If the pasted image is too large, then I have to maneuver it back and forth within the window to size it appropriately. Very inconvenient!
