• WONTFIX: Accessibiltiy issues stemming from <th> and <td> in the same <tr>. Users have to use headers to fix this.

• CHECK: Breadcrumb doesn't need role="navigation", it's already a <nav>.
• CHECK: Alert doesn't require role="alert", it might not behave like one.

[Chalarangelo]

• CHECK: Menu and its associated MenuItem do not require the menu and menuitem role as the implementation does not work with certain keyboard controls necessary for those roles. Menu uses a <nav> element internally and its children are already semantically correct.
