The way it was done involved remembering dom nodes and then getting their position later when animating the receipt to its next position, but I'm not sure how this worked since the DOM node may not neccessarily be in the DOM anymore. Instead, just remember the bounding box coordinates. At worst it might go weird if the window is resized but seems fine in practice. Also, keeping references to dom nodes feels like a fast road to memory leaks.

Fixes element-hq/element-web#27916
