Fix IE7 problem with the views interface after latest MochiKit upgrade.

NOTE: this fix was cherry-picked from master after the same bug was discovered
on 1.0_STABLE. It looks like it wasn't the mochikit upgrade on master that
caused the issue, but that doesn't matter because the fix works everwhere.

(cherry picked from commit 9550e111)
