Dropdown lookup field not responding to keyboard

[sclg]

Just updating an app from v2020 to v2024.
First field on the add page is a dropdown for a name lookup. Assuming that field has focus, in the old version, if I type any letter on the keyboard then the list will go to the first entry starting with that letter.
In the 2024 version, nothing happens when I type a letter.

Any ideas?

The selection lists are Select2 widgets by default, not native HTML selection lists. If you don't need the features of Select2 and prefer native behavior of selection lists, and your selection lists are select-one (not select-multiple), then you may enable Use native SELECT tag for select-one fields.
