The addition of file labels breaks the layout of Tools->Attachments View when files have multiple versions

Running 4.2-beta3, the addition of the new Attachment Label feature is disturbing the layout of the Attachments View when files have multiple versions.

The columns are lined up correctly when there is only one version of a particular file, but when multiple versions of a file are uploaded and the triangle is selected to expand the revision list, the comments for the non-current revisions appear in the "labels" column and the remaining columns do not display correctly.

Luckily, the

{attachments} macro itself renders correctly. It is only the built-in attachments view (viewpageattachments.action) that suffers this bug.

attachments-page-expanded.png shows the error in action. attachments-page-normal.png shows what the page looks like before expanding the triangle.

The complementary set of attachments-macro-*.png files show the view from the {attachments}

macro. This works normally and I have included it only for reference.
