Move/copy dialog on web

Nextcloud version: 18.0.4 and 19RC1
Operating system: alpine (setup copied from official docker image fpm-alpine)
Apache or nginx version: nginx/1.16.1 (fpm-fcgi)
PHP version: 7.3.18

The issue you are facing:
After installation the “move/copy” file dialog does not appear. nothing happens when i click the three dots and select “move or copy”. everything else seems to work.
i can move folders through drag and drop, webdav and desktop/android client.

Is this the first time you’ve seen this error?
yes

Steps to replicate it:

  1. this is my install script: https://github.com/flower1024/nextcloud/blob/master/app/post/root/nextcloud.sh
  2. please not that i have the same effect directly after OCC maintencance:install without the other steps in there
  3. there is an example compose file inside readme.md if you want to get a live example. i currently test without the read_only line though

just found that line in my nginx log. it seems unrelated to the actual click on that menu option though

Which browser are you using? FF, or?
Tried another?
Using add-ons like script blocker?

i have tried with chromium and ff.
disabling adblocker in ff didnt change anything (dont have one in chromium)
