Before: ![image](https://github.com/go-gitea/gitea/assets/18380374/ba69252f-3582-414a-9d62-b2b78d7035dd) After: ![image](https://github.com/go-gitea/gitea/assets/18380374/71b8587c-b96e-48fb-b3e5-1a2a8b5d06fa) (TestOrg:test is a tag not branch) Problem: In the template, we will not add `compare pull` class when `PageIsComparePull` is false. a370efc13f/templates/repo/diff/compare.tmpl (L2) But in the js, we are using `.repository.compare.pull` to find the button: a370efc13f/web_src/js/features/repo-legacy.js (L552-L563) So, if `PageIsComparePull` is false, the `New Pull Request` button will be there, but has no response when we click it.
