[Feature Request] [tooltip] Make it possible to update popper

### Existing Component
Yes

### Component Name
Tooltip

### Description
Watch content value for change and in case of change, update popper.
or
Make **updatePopper()** internal function a public method of the component.

### Example use case
"Copy-to-clipboard" button with a tooltip content that encourages the user to click on it, like "**Press to copy to clipboard"**.
As soon as the button pressed, the tooltip that is still visible changes it's content to "**Copied**". Unfortunatelly right now, the whole position is off, as there's not way to call popper to update the positioning.
