I don't have collapsible job log although am using the latest GitLab version

I’m using a self-hosted GitLab instance, and it’s still showing the old non-collapsible job logs instead of the new one I observe on GitLab.com. I keep getting curious upon every update and I just updated to 12.5.0 and it’s still the old behaviour. Am I missing something?

After updating to 12.7.4, I suddenly got the collapsible job logs. Don’t know what was stopping it from showing up, but the issue is resolved anyway.
