Ionic Framework Version

v8.x

Current Behavior

The value attribute isn't causing the knobs to be placed where they should be if the ion-range is in a modal

Expected Behavior

I would expect that the lower knob is placed at range 20 and the upper knob is placed at range 80

Steps to Reproduce

1. Add an ion range to a modal
2. Assign the value attribute to something that you expect
