On first render (previously), transitionToRef did not have a scrollHeight value.

Renamed to keep naming consistent with all transitionFrom values having a prev prefix for clarity.

Using the transitionFromRef.current.containerHeight won't be as accurate, as it could have changed from a manual resize between animations. Relying on containerHeight will be more accurate.

Fixes #67360
What?
When animating between zoom levels, we were forcing a scrollbar during the
positioned: fixedpart of the animation to prevent a width snap. However, this assumes the container always has a scrollbar, which isn't true. To fix it, we only add the scrollbar into the frame if necessary.Why?
Improve layout animation when the editor canvas does not have a scrollbar.
How?
