Description
Currently MaterialButtonToggleGroups configures its children with `buttonChild.setEllipsize(TruncateAt.END);` Thus it is not possible to use other types of ellipsization, most prominently TruncateAt.Marquee. For long button texts, marquee gives the possibility to discover the full button text, which is often necessary for usability.
Ideally, the ellipsize attribute set in xml would not be overriden. I understand that with the current implementation this would not work out of the box, because marquee breaks the layout, and more work is needed to support this.

Research direction
Start with the MaterialButtonToggleGroup implementation and the child button ellipsize configuration described in the issue. Inspect how the XML ellipsize value is currently overridden and how marquee affects the group's layout. Done means supporting non-END ellipsization, including marquee where feasible, without breaking the layout, with tests covering the behavior.
