The InkBar was not checking to see if the controlled
value
was set before using the uncontrolled internal state ofselectedIndex
.selectedIndex
gets updated on every click, but it should be ignored when tabs is setup in a controlled way.My use case was setting my tabs as hyperlink (
<a/>
tags), and if a user opened the link in another browser tab, it would keep the correct tab highlighted (text color wise) but the inkbar would move to the tab that was just clicked.I also updated the tests and added one for my case to test the highlighted tab and inkbar location instead of just the internal state.
