Drag & Drop assignment of Contacts only works reliably when marking the contact first.

[kaibrockelt]

Describe the bug

Hi NC Fam!

I found a weird behaviour that "most of the times" when dragging and dropping contacts, without priory highlighting of the entry.

I was able to reproduce this on Brave / Chromium engine, Safari and Firefox. Seems a global issue, not browser-related

Steps to reproduce

1. Go to 'Contacts'
2. Have a group you want to add users to
3. go to "ungrouped Contacts', directly drag and drop users into the new group
4. It seems like the change is committed, however, when reloading, most of the contacts added to the group won't be stored.

Expected behavior

Contacts should be saved properly, as the UI indicates.

Actual behavior

Contacts are displayed in the group until you reload. Changes then are gone.

Contact version

8.3.7

Operating system

osx

PHP engine version

PHP 8.3

Web server

Apache (supported)

Database

PostgreSQL

Additional info

As this is easier to understand by seeing the behaviour, ive created a short screencast demonstrating.

Hello,
Thank you for the really thorough report and the video,
I think you're trying to drag and drop readonly contracts. (system address book contacts ) which doesn't work.
Can you please confirm/decline my hypothesis?

[kaibrockelt]

Hi Hamaza,

I'd decline this hypothesis in this case. The ones you see have been uploaded via contact book file which i generated. (attached as code, save as vcf file)

I however initially experienced this issue on my "real" instance of nextcloud, where i synced in the contacts via apple contacts integration on my laptop. The test instance you see in the video is completely stand alone, and besides the contacts uploaded "clean".

Besides, as the video shows, the contacts are not read only, as dragging works super reliably when first highlighting the list entry. I would expect this not to work neither if the contact was read only.

Meanwhile i was also testing my race condition hypothesis a bit and did the job "really slow", like having the drag take 3 seconds. But the behaviour stays the same. So there must be some other kind of fuzziness going on.
