Button Misalignment in Pull Request Section on Core Trac

[parthvataliya]

In the Core Trac site's pull request section, when the pull request title and username are lengthy, the "View patch" and "View PR" buttons are misaligned. This breaks the structure and affects the overall user interface.

Steps to reproduce:

1. Navigate to the pull request section in Core Trac.
2. View a PR with a long title and/or username.
3. Observe the misalignment of the buttons.

Expected behavior: The "View patch" and "View PR" buttons should remain properly aligned in the same row, regardless of the length of the PR title or username.

As shown in the screenshot, the buttons are not staying within the same row, which could negatively impact user experience, especially for users viewing detailed PRs with longer titles or usernames.

Trac: Better visual style for GitHub PRs when the content wraps.

Noting for future reference that the Core Trac ticket from the associated screenshot is ​https://core.trac.wordpress.org/ticket/59960.

While this could happen with any row field being long, I feel that this is mostly due (at least for this ticket) to the third column being long (with "✅ Unknown, Approved" as it had at the time of the screenshot, or "✅ All checks pass, Approved" as it does now).

Trac: Prevent nowrap from applying to message in "Pull Request" section when there are no pull requests to list.

Ensures nowrap style only applies if there is more than one div present, which would only be the case if a PR was being shown.
