Author Name Hidden in Post Editor When Permalink Is Too Long

[alexdeborba]

Description

When creating or editing a post in WordPress, if the permalink generated is too long, it causes the author name to be hidden or truncated in the post editor interface. This issue was observed when editing a post titled "Gaerea: 'Coma' as a Reflection of Existential Turmoil in Modern Black Metal."

Step-by-step reproduction instructions

1. Create a new post with a long title.
2. Observe that the permalink generated is long.
3. Notice that the author name is hidden or partially visible in the editor's right sidebar.
