form-select[multiple] should not display any indicator/icon
Created by: tkrotoff
Under Bootstrap 4 (4.6.0), custom-select[multiple] does not display the select indicator and the is-valid/invalid icon:
<select class="custom-select is-valid" multiple></select>
Under Bootstrap 5 (5.0.0-beta3), the new form-select[multiple] does display the select indicator and the is-valid/invalid icon:
<select class="form-select is-valid" multiple></select>
This is a regression.
