Unable to view wiki pages in UI that contain empty spaces
Summary
Since GitLab version 15.5, it is no longer possible to preview the wiki pages that have a space ( ) in their names.
In GitLab version 15.4 such pages can be opened without issues. I suspect that this change might have introduced a regression.
Steps to reproduce
- Install GitLab 15.5+ or use GitLab.com
- Create a project and commit+push a wiki page that contains a space in its name;
- Try to open this new or link it from a different wiki page, and you will be prompted to Create a new page instead.
Example Project
This Home wiki page contains a link to a file that can't be displayed, but it exists in the wiki repository: https://gitlab.com/gitlab-gold/kategrechishkinatestgroup/wiki-test/-/wikis/Home
The project contains a file Analisi Statica.md which can be viewed if the same wiki project is pushed to a GitLab instance version 15.4 and lower.
What is the current bug behavior?
Navigating to a wiki pages that contain empty spaces gives "Create a new wiki page" screen instead of displaying a page.
What is the expected correct behavior?
The page should be displayed as it was the case in GitLab 15.4-
