Slider List Item (oh-slider-item) incorrectly rounds displayed value

[BentHaase]

The problem

The 'Slider List Item' (oh-slider-item) incorrectly rounds the displayed value to the nearest integer value. This behavior started with 'some' Update a few months ago. Before this, the selected value was shown.

See this screenshot of the issue:

Code for the specific slider:

value: oh-slider-item
config:
  commandInterval: 2000
  delayStateDisplay: 20000
  icon: oh:heating
  iconUseState: false
  label: true
  max: 30
  min: 4.5
  releaseOnly: true
  scale: true
  scaleSteps: 1
  scaleSubSteps: 10
  step: 0.5
  title: Thermostat Temperatur
  unit: °C

Expected behavior

Like before the value displayed to the right should show the correct fractional value that has been slected via the slider (or any other source).

See this mock up of how it 'once' was and should be:

Steps to reproduce

1. Add Device / Item to model
2. Set 'Default List Item Widget' to oh-slider-item
3. Set a step size of 0.5 (check code snipped above)
4. Select a value of x.5 via slider item and check displayed value to the right with the value that was set

Add:

  footer: =JSON.stringify(items.YourItemName)

to your widget to make sure there isn't a unwanted "displayState":

I have the 'inverse' problem with current OH4 (S3515): when I set a value via slider, the item is correctly set. But the slider position graphically resets to the next-lowest integer. Item correctly remains as just set.
