Text truncation in selected select

Dear Ionites,
I’m trying to show full text of the selected option but text-wrap doesn’t work.
I used the following css to achieve that into the alert with the select options, but cannot make it work after the selection has been made.

.alert-tappable.alert-radio {
    height: auto;
    contain: content;

.alert-radio-label.sc-ion-alert-ios {
    white-space: normal;

Anyone can give me a tip on how to do that?
