Link fieldtype allows multiple assets per drag and drop #12033
Description
Bug description
When adding multiple assets per drag and drop to a link field, it keeps all three instead of just one. After saving there's only one left. The asset fieldtype (with max_items set to 1) also allows that, but throws a validaton error on save, so editors have a little more control over which assets they need to delete.
There are kind of two minor bugs in this issue: The behaviour of being able to upload multiple assets into the asset fields and the different behaviour of validation of the asset fieldtype component and the link asset component. Both are confusing for editors, but I think having the same validation with both components would already help a lot. I can open another issue if that's better.
Here's a screen recording of the behaviour of the link asset component:

How to reproduce
- Set up a fresh Statamic
- Add a link fieldtype to any blueprint
- Drag and drop multiple images into the upload area
