The 17.0 major release is coming on May 16, 2024! This version brings many exciting improvements to GitLab, but also removes some deprecated features. We are introducing three breaking change windows during which we expect breaking changes to be deployed to GitLab.com. You can read more about it on our blogpost. The second breaking change window begins 2024-04-29 09:00 UTC and ends 2024-05-01 22:00 UTC.
I do not know anything about the templating system used by gitlab but the enclosing patch should be close to the fix for #1019 (closed).
I do not have any installation of gitlab nearby to test it.
Just hope that I will not have to wait 7.8.0 to have a fix for this :)
