Description

This issue is a continuation of https://github.com/dotnet/maui/pull/18813

if our Gallery if you use the following galleries (especially the horizontal one)

you'll see that loading takes a really long time.

We added code inside the templated controls to return a default minimum but I'm guessing this problem still manifests from non templated columns because the minsize for ListItem is zero
