[Bug]: Resolving a conflict when uploading multiple files via drag-and-drop cancels all uploads

⚠️ This issue respects the following points: ⚠️

• [X] This is a bug, not a question or a configuration/webserver/proxy issue.
• [X] This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• [X] Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• [X] I agree to follow Nextcloud's Code of Conduct.

Bug description

• When I drag two files into the web interface
• and one already exists on the server
• and I resolve this conflict using either "Skip" or "Keep old file"
• all uploads are cancelled, including ones which do not conflict.

Steps to reproduce

1. Have two files. Upload one to the server.
2. Drag both into the folder. Encounter conflict resolve dialog. (Using the "Upload files" file picker dialog, this issue does not occur.)
3. Resolve conflict using "Skip" or "Keep".
4. The unconflicted file fails to upload too.

Expected behavior

The non-conflicting files should be uploaded regardless of how the conflict was resolved.

Here is a video of the issue, showing that even some resolutions stop the upload. I know @skjnldsv touched this area, perhaps he can have a look.

Hi, same issue on 29.0.6.1

Hello, Detected behavior when a conflict occurs when uploading existing files to the Nextcloud server.

Using the drag and drop option:

• If you choose Select all existing files the new files are not uploaded.
• If you choose to update at least one of the conflicting files, that file is uploaded, as well as the new files.

Using the Upload files option:

• New files are never uploaded, regardless of whether you choose to keep or update any of the conflicting files.
• Messages are never displayed (Conflicts resolution skipped, No files to upload, Files uploaded successfully)

Tested on versions 29.0.8 and 30.0.1.

Thanks.
