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

https://uppy.io/examples/

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)

Not sure why but I can't reproduce this locally for the website nor in another dev setup 🤔

However I did found a bug where the Url plugin tries to fetch the link when dropping the same file.

Did create a streamable on your example website.

Why did you close this?

From what I understood, you only fixed the Companion warning, correct? The original bug is still present from what I tested just now.

I put a streamable because the reproduction is literally in your example page. I don't believe I can do much more on my end.
