I believe this is the general behavior of in-page accesskeys.  They override all other shortcuts bound to the same modifiers....  The problem is that most people have no idea the Ctrl-u shortcut even exists on Mac textfields, and would be very surprised if it got triggered when they're just trying to trigger an accesskey.

They would learn the Ctrl-u shortcut at this time...

The best solution would be to avoid this clash by choosing a different modifier for accesskeys. Otherwise this could be controlled by options.

Note: the page has changed, so that this bug is no longer triggered by this page.

The problem of keys overridden by other uses is also mentioned in bug 276295 (this one for FAYT).
