Review Comment:
Gauge updates no longer use the old Gauge-specific merge, but
`GaugeChartConfig` is absent from `_MODELED_UPDATE_CONTROL_PATHS`. A partial
Gauge update therefore maps defaults such as `show_progress=True` and
`split_number=10` over saved non-default values; can Gauge be included in the
modeled update semantics and covered through `update_chart`?
