read_only_slider-option for the slider button has no effect

[Soukyuu]

Describe the bug
The YAML option read_only_slider seems to have no effect

To Reproduce
Steps to reproduce the behavior:

1. Create a slider button
2. Assign to any numeric entity
3. Add read_only_slider: true to the card as a YAML parameter
4. Attempt to change slider value
5. Value changes despite read_only_slider

Expected behavior
Value not changing because read_only_slider is set

YAML

type: custom:bubble-card
card_type: button
button_type: slider
entity: input_number.uv_1h
show_state: true
name: UV Index
styles: >-
  * {
    --bubble-border-radius: 8px;
  }

  .bubble-range-fill {  
    background-color: rgba(${state > 7.0 ?  '190, 0, 0' : state > 3.5 ? '255, 150, 0' : '0, 80, 0'}, 0.4) !important;
  }

  .bubble-icon {
    color: ${state > 7.0 ? 'red' : state > 3.5 ? 'orange' : 'green'} !important;
  }


  ${card.querySelector('.bubble-state').innerText = state + ' / ' +
  hass.states['sensor.uv_maximaler_uv_index'].state}
card_layout: large
show_last_changed: false
read_only_slider: true

Informations (please complete the following information):

• OS: [e.g. iOS]
• Browser/App: [e.g. chrome, safari]
• Bubble Card version: 3.0.0-beta9
• Home Assistant version: 2025.5.3

Additional context
I saw the option in multiple examples of configurations, but it seems to be missing in the docs? Was it maybe removed? It'd be pretty useful to me.

Hi! The doc is not yet updated for v3.0.0, that's why you haven't found it.

I just tried and this is working on my side, you probably don't have v3.0.0 installed, there is currently a bug with HACS that download the latest version (v2.4.0) instead of the beta in some cases. You can check the version in the editor, at the bottom, or in your browser console.

Yes, that's exactly it, issue does not exist.
