Reporter user can't access to wiki trough the UI only by the url

Hi everyone,

I create a wiki page.

My client is set as Reporter.

My client can access to the wiki I created through the URL.

My client cannot access to the wiki while following this path on the gitlab website:
<project name>/<repo name>/wiki/.

It’s appear to be a UI issue. In fact, the grey part on the right which usually list the differents wikis does not appear.

I hope I am clear enough.

Please feel free to ask me for more details if necessary.
