Hidden space in filename not seen in file listing

Steps to reproduce

Create folder, then file. In my case "Name - Subname .gpx", make sure the leave the extra space between the word "Subname" and the ".gpx".
Once file is created, reload page. You should see the filename does not have the trailling space anymore if it's not being edited.
Once you start editing the file name, the trailling space re-appears.

Expected behaviour

I expect to see the trailling space in the file name even when not editing the file name but when listing all the files of a folder. I want to be able to see the files in a folder with their correct filename even if it has space in it.

Actual behaviour

Instead I only see the trailling space in file name when either editing the filename via NextCloud web interface or when another NextCloud app is listing this file. Other wide I would have neven noticed the extra space.
