• Tooltip position throttle makes tooltip feel laggy #16101

Details

Before: What was the problem?

We throttled the updatePosition function of tooltip in #15683 to solve the shake and lag issue(raised by #14965) in Chrome(with DevTools open) and Firefox. But as #16101 described, the tooltip will be laggy because of the 50ms interval when transitionDuration is 0.

Refer to #16101, #16091 for more details.

After: How is it fixed in this PR?

Throttle it only when transition is enabled.
