[GAMEPLAY] Using Tahm Kench ultimate doesn't make it appear to be on cooldown for team mates.

After using Kench's ultimate to reach a new location, and putting the ability on cool down, the ultimate ability indicator for kench located above the mini map will continue to display the ability as being ready for all other members on the team, despite having been put on cool down. The ability works perfectly as intended, however teammates will see it as being ready when it is not. I have a tendency to button mash when using it for myself, though I don't know if this is a factor in causing it.

Steps to causing:

1. Target a location with the ultimate.
2. Have a teammate, or second cast trigger the travel.
3. Your teammates will continue to see the ability as being off cooldown, despite having just used it.

I have been seeing this problem occur since around the release of kench, though it does not seem to occur in every game, or even happen with every ultimate cast within a match as kench. I only know this bug exists because of chatting with both friends and teammates who report it as appearing off cooldown when it is not.
