`defaultFormatter` overwrites custom `label_min`/`label_max` for `DecimalRangeField`

[HolgerGerhardt]

Say, you set

label_max=safe("<span class='text-success fw-semibold'>My entire<br>budget</span>"),
label_min=safe("<span class='text-danger fw-semibold'>Nothing<br>at all</span>"),

for a DecimalRangeField, like in https://github.com/mrpg/uproot-examples/blob/master/input_elements_and_typography/__init__.py. This is currently overwritten by the defaultFormatter from uproot.js.

In addition, the JS-based formatter influences the width of the max and min labels. This makes DecimalRangeFields with anchoring=False become too narrow or too wide, taking the width of the labels into account.
