Lit slider - value not updating

[lukasmoschitz]

Summary

The Lit slider component does not update its value when the slider is moved.

Expected behavior

Dragging the slider should emit updates and reflect the new value visibly.

Reproduction

1. Render a slider with a path to data
2. Move the slider
3. Observe that the value does not change / no update is emitted
