Title: Fix for tooltip disappearance

The bug occurs when using tooltip with hide delay that is longer than show delay, for example:

```js
delay: {
show: 0,
hide: 200
}
```
If we quickly do mouse enter, leave and enter again our tooltip will get instantly showed but then hidden because the hide timeout is not cleared.
