## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

In the custom elements build, currently used by React and Vue packages,
the range knob can be rendered incorrectly if the value is assigned
after the `connectedCallback` but before the initial render of the
component. This is most apparent with the dual knobs implementation in
React (referenced issue).

This results in the range's value being correct, but the visual
representation of the range to be incorrect.

This also causes issues with the custom elements build in the standalone
implementation of Ionic's components in Angular. If a range is presented
in a modal via a controller, the range will never render with the value
that is initially assigned to it.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Updates the range knob positioning when the range has initially
rendered.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->


## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->

This change needs to be pulled into the Ionic angular standalone work.
