There is something wrong going on in Special:SiteMatrix. When a language lacks translation to the users interface language and it has the opposite direction, the parentheses are broken.
Example:
https://en.wikipedia.org/wiki/Special:SiteMatrix?uselang=fr
In the first column the description for the row with arz is broken. It says:
مصرى (مصرى)
Example for the opposite direction:
https://en.wikipedia.org/wiki/Special:SiteMatrix?uselang=ar
The row with Alemannisch is broken. The same is the case for many other languages.
Version: unspecified
Severity: normal
