Actual Behavior

While investigating #2040 I came across an issue with the rendering of completed uploads:

I did find one thing which we are doing wrong, though I don't think it fixes your issue. It's supposed to stop showing the progress bar when the upload is done and show a check mark instead. That doesn't happen because we are overriding the complete function instead of adding a secondary event handler. Therefore the default complete behavior is not called and the dz-complete class never gets added.

#2040 (comment)

The checkmark animates in for a moment and then goes away. The upload bar remains.

Expected Behavior

This is what it's supposed to to look like, according to the Dropzone documentation.

Steps to reproduce

Steps:

1. Click "Upload File"
2. Upload a file

I'm playing around with what what the UI for a completed upload should look like. I was mistaken when I said that the checkmark is supposed to remain visible. In fact it animates in and then disappears (bottom left).

We could choose to keep the ✅ visible, though if we do that we'll want to move the file name down to the bottom so that it isn't covered up. I'm also playing with some CSS color changes on the top 2.

The white circle checkmark (bottom right) is the default UI for the version of dropzone that we have currently. If we upgrade to a newer version then the default changes to a black circle with a white checkmark, which is mush easier to see. The new version has sharper edges in addition to the color change.

Regardless, we have to option to use our own custom✅, or to adjust the colors via CSS.

Pinging @shujuuu -- this is not important but I'm curious if you have any thoughts.
