Simple ComboBox: Filter is sometimes not applied

[altju]

Description

If the dropdown of the Simple ComboBox component has not been opened before, the filter is not applied when typing the first character.
When entering the first character, the dropdown opens and after typing the second character, the filter works as expected again.

• igniteui-angular version: tested with 16.0.13 and latest version of demo page
• browser: any

Steps to reproduce

1. Go to the demo page of the Simple ComboBox component: https://www.infragistics.com/products/ignite-ui-angular/angular/components/simple-combo
2. Clear the current pre-selected value "CubicFit" (x-icon)
3. Filter by typing any character, e.g. a "c"

Result

The dropdown opens but the filter is not applied. All values are shown.

Expected result

The dropdown opens but the filter with the value "c" should be applied so that in this example only 5 values containg a "c" are selectable.
