Accept is working different as in documentation

[BernhardBehrendt]

I'm testing actually using the DEMO in Angular 15

Generally the drop zone accept when dropping any format, folder and multiples regardless whats configured.

But when showBrowseBtn is enabled then the configured rules are working within the File Selection window. Except format.

When I set e.g. accept=".pdf" as format I can select everything. If I set accept="application/pdf" it's working for the file window.

But as explained all is not applied on the Drag&Drop itself.
