### Summary When viewing a file, clicking the "Permalink" button will cause the previously-selected line reference (e.g. `#L32`) to be dropped from the URL. This happens when the user selects a line by clicking the "link" icon instead of the actual line number. ### Steps to reproduce 1. Navigate to a file view, i.e. https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/views/shared/milestones/_sidebar.html.haml 1. Select a specific line by clicking on the link icon next to the line number. Notice that a URL parameter like `#LXX` has been appended to the current URL in your browser's address bar. 1. Click the "Permalink" button ### What is the current *bug* behavior? The new URL no longer includes the `#LXX` parameter. ### What is the expected *correct* behavior? The new URL should still contain the `#LXX` parameter that existed before the "Permalink" button was clicked, regardless if the line was selected by clicking the "link" icon or the actual line number. ### GIF  ### Output of checks This bug happens on GitLab.com.
