Error:

    at proxyCustomElement.disabled.open (@ionic_vue.js?v=95484b8b:14363:19)

Expected Behavior

There should be no error.

Utility:

System:

Additional Information

I'm seeing this in both Brave and Firefox, M1 MBP.

The cause:

• popover.js#present calls attachComponent, passing the string 'ion-select-popover' as the component argument.
• attachComponent calls attachViewToDom, which tries to use that string as the key to a weak map, which doesn't work.

FYI, I did some testing with earlier versions and the bug appeared in 6.4.
