What happened?

Description

I have an Entry::EVENT_BEFORE_SAVE event in which I do:

$entry->setFieldValues([
    'latitude' => $coords['lat'],
    'longitude' => $coords['lng'],
]);

This works when updating entries, but not for the case where $entry->firstSave is true.

Steps to reproduce

1. Create an event listener that sets entry field values.

Expected behavior

It should work on first save.

Actual behavior

The first time saving it doesn't work, on updating it does.
