Prerequisites

Ionic Framework Version

• v4.x
• v5.x

Current Behavior

After clicking onto an ion-select with interface="popover" the backdrop appears but no popover is shown. The console shows the error or rather warning “Found a ‘popover’ attribute with an invalid value.”

Expected Behavior

After cclicking onto an ion-select with interface="popover" the backdrop AND the popover itself should be shown.

Steps to Reproduce
