fix(runtime-core): Make transition behavior in KeepAlive in dev-mode consistent with production-mode.

[ygj6]

fix: #5500
In this example, click Page A and then click Page B. Page A moves to the left, which is inconsistent with the name of the Transition node.This is due to the fact that

core/packages/runtime-core/src/componentRenderUtils.ts

Lines 221 to 229 in 5898629

	if (vnode.transition) {
	if (__DEV__ && !isElementRoot(root)) {
	warn(
	`Component inside <Transition> renders non-element root node ` +
	`that cannot be animated.`
	)
	}
	root.transition = vnode.transition
	}

It adjusts the position of the transition, so the last transition is used when moving. Now let's update it manually

Not exactly, because components are not uninstalled in keepalive, but I believe there should be a similar problem in 5268.
