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

**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.
