Current behavior
When I navigate to a component which has a TabView with :activeIndex.sync, passing an active index greater than 0 in a prop, the following errors show in the browser's console:

Looking at the trace of the error, I went to the method updateInkBar of TabView.vue, and saw that it is called both in mounted() and in updated(), and the error happens only in mounted().

Expected behavior
It doesn't seem to break anything, but there should also be no errors in the console.

Minimal reproduction of the problem with instructions
In the codesandox I provided, just navigate from the home page to any of the tabs, using the buttons. You'll see no errors when navigating to Tabs0, but the errors will appear when using Tabs1 or Tabs2.
