[Feature]: Allow selection when pressing Tab in Select

[pmairoldi]

Describe the feature

When looking through the w3c patterns documentation and playing around with the native HTML select it seems like Tab has some behaviour attached to it that is not present in this library.

The behaviour is that when Tab is pressed, the current "active" value should be selected and then the focus should either move to the next focusable element or the select trigger. I see that the Tab key is disabled on purpose so I was wondering if this would be something that the library should support.

Thanks for the great work!
