Select: .p-select class does not exist at first launch

[florianjea]

Describe the bug

I have a styling issue with my Select. When I deploy a new build or open the local server (yarn dev) in a new incognito mode window, the style of the “p-select” class cannot be found in the styles when I inspect the page. The Select looks like this:

At first launch	After a refresh

What's strange is that the other components have absolutely no issue with their styles. Only Select.
