IE9: Object doesn't support this property or method "replaceState"

[clevergod]

Version

3.0.1

Reproduction link

#1834

Steps to reproduce

IE9 throw the following error： Object doesn't support this property or method "replaceState"
I set the options: fallback: false
I saw a similar issue：#1834
Why not do the same treatment here?：

vue-router/dist/vue-router.js

Lines 2149 to 2153 in 8dadf97

	var expectScroll = router.options.scrollBehavior;
	if (expectScroll) {
	setupScroll();
	}

What is expected?

In addition to the judgment support supportPushState processing：

vue-router/dist/vue-router.js

Lines 2149 to 2153 in 8dadf97

	var expectScroll = router.options.scrollBehavior;
	if (expectScroll) {
	setupScroll();
	}

What is actually happening?

It seems that it has been fixed but not published to npm yet.
