[Bug Report] Setting active tab after removing an tab from array causes selection offset

[MajesticPotatoe]

Versions and Environment

Vuetify: 1.1.8
Vue: 2.5.16
Browsers: Chrome v68
OS: Windows 10

Steps to reproduce

Click on an X button to close a tab. (as noted below, closing the last tab functions properly)

Expected Behavior

The tab should close and the last tab should be selected.

Actual Behavior

The slider bar selects the correct tab However the active tab is the 1 index behind. When clicking the tab with the slider, it behaves as if it was the active tab (nothing happens).

Additional Comments:

This behavior does not happen when iterating through active tabs (like in docs) or if you remove the last tab. Have also tried doing async/await but everything seems to debug as if its functioning normally.

One thing to note that may need a new ticket is that if you remove all of the tabs from the array, the slider bar still remains.

Possibly related. Closing all tabs leaves GUI artifacts.

• Select tab 2
• Close all tabs
