Current behavior:
If we try to use Ion-select with interface="popover" the performance is very slow. However when we use other interface type such as default one the performance is better for the same set of data.

Expected behavior:
We expect the same performance for all the interfaces available in ion-select.

Steps to reproduce:
Use the control type ion-select with interface="popover" and dynamically render the same control type ion-select 5 times in the web page with each element having 1500 options.

Thanks for the issue. I am going to close this as a duplicate of #17641.

However, please note that this is not really the intended usage of ion-select. It would be better to place these 1500 options in a modal that uses virtual scroll.
