Changing start/end of gauges does not cause re-render

[NotTsunami]

Describe the bug Changing start/end of a gauge does not cause a re-render, but changing a Pointer value does. I filed this under bug report as I would expect this to be out of the box behavior, but it can also suffice as a feature request.

To Reproduce See reproducible code.

Expected behavior When the start or end values are changed, the gauge is expected to respect these values and re-render.
