This seems totally odd but we've reproduced it on 3 Firefox installations (one with a fresh profile):
1. Open Firefox (tested with Firefox 129 and 130)
2. As an admin/moderator, go to the Approval queue page of your forum
3. Ensure that there are at least 2 posts that need approval
4. For the first post, select the "Approve" radio button
5. Click the "Save" button
What should happen: After saving, the page should show the remaining posts that need approval and all posts should have their "Do nothing" radio button selected.
What actually happens: After saving, the page shows the remaining posts but for the first post the "Approve" radio button is pre-selected automatically.
This issue only exists in Firefox, not in Chrome. It is actually more general than described above: If you select the "Approve" radio button of the n-th item then after saving the "Approve" radio button of the n-th item will be selected automatically. Furthermore, it doesn't only work with "Approve" but with "Delete", too. So this issue can lead to moderators accidentally approving and deleting posts.
