Bug - Truncate - tooltip also shows when there is no actual truncation

[mvollmer]

The Truncate component always has a active tooltip for its content, even when there is no actual need for truncation:

Such a tooltip doesn't contribute anything to the user experience, but is an annoyance especially if there are many of them.

It would be great if Truncate would only have a tooltip when truncation does actually take place.

Alternatively, as a lesser alternative, a property would be welcome that allows the programmer to disable the tooltip completely.

If the full text is visible then it can be an unnecessary distraction to have tooltip flashing up so I think we can address this.
