Which component(s) are affected?

Combo

Description

When the Combo data is set after the initial update of the component (e.g. from async request), the defaultValue isn't reflected due to the data setter re-assigning value which takes the component out of pristine state.

There's possibly more to be done regarding

Reproduction

combo_defaultValue.zip

Run the attached sample and select and order from the side combo to populate the form. Combo reflects the default value only after reset.
OR
In on any Combo - set data and then defaultValue after, e.g. on https://igniteui.github.io/igniteui-webcomponents/?path=/story/combo--form

$0.data = $0.data;
$0.defaultValue = [$0.defaultValue.at(0)]

Workaround

None

Is this a regression?

No or unsure. This never worker, or I haven't tried before.
