fix(button): avoids overflow

[soymartinez]

Fixes #416

This PR avoids the overflow of the whole window when the button is not in the viewport and the content has some absolute position.

---

The problem starts with the sr-only property of the span tag inside the Button component which is the Trigger of the DropdownMenu.

By setting the relative position in the Button component we limit the content of any absolute position and in this way it is not necessary to limit the whole table or any parent tag.
