PDF.js cannot open file with space (%20) in URL

[s4g1n0]

This looks like some error in escaping of URL containing "%20", as this is escaped into "%2520" and then file is not found.
Original directory URL: https://example.com/index.php/apps/files/?dir=/abcd/test/Documents/Testing%20Directory&fileid=1852584
Broken PDF file url: https://example.com/remote.php/dav/files/abcd/test/Documents/Testing%2520Directory/202105.pdf

Steps to reproduce

1. Open whatever directory with space in name
2. Try to open pdf in that directory

Expected behaviour

PDF will be loaded inside PDF.js in browser

Actual behaviour

PDF.js loads with error message:
PDF.js v2.5.207 (build: 0974d6052)
Message: Missing PDF "https://example.com/remote.php/dav/files/abcd/test/Documents/Testing%2520Directory/202105.pdf".

Are you using external storage, if yes which one: smb

Are you using encryption: no

Are you using an external user-backend, if yes which one: LDAP

LDAP configuration (delete this part if not used)

LDAP config

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your Nextcloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Client configuration

Browser: Opera, Firefox
