Dragging already added file and dropping it, duplicates file

[gongAll]

Initial checklist

• I understand this is a bug report and questions should be posted in the Community Forum
• I searched issues and couldn’t find anything (or linked relevant results below)

Link to runnable example

Steps to reproduce

• Add .png file
• After being added, drag file around
• Drop file when prompted to do so ("Drop files here" appears)

Expected behavior

Should not allow to drop file. Perhaps should allow to reorder files instead, when files have already been added.

Actual behavior

Result: File is duplicated how many times I do it (literally to infinity)

PS: I had already created an issue for this, but it was closed without a response: #5622 (comment)

It no longer happens in Chrome and Firefox and thus it seemed fixed. Only in Safari I still see it happen.

I did just reproduce it locally on Brave, which is Chromium based.
