Set the `transform-origin` of the `Popper` / Tooltip classes for transitions that scale.

Object.assign(popover.style, { position: strategy, left: yOnly ? "0" : px(x), right: "auto", top: px(y) });

Based on the placement you should set the transform-origin as well so that when a transition is enabled that adjusts the scale or rotate the transition starts from the correct place instead of in the center (default of transform-origin).

Can be done by doing something like this (copied from my own implementation of floating-ui):

	Object.assign(popoverElement!.style, {
				left: `${x}px`,
				top: `${y}px`,
				transformOrigin:
					{
						top: 'bottom',
						bottom: 'top',
						left: 'right',
						right: 'left'
					}[placement.split('-')[0]] || 'center'
			});

If not desired then give the option to adjust the popover style based on properties like placement so people can do it themselves.
