+  CSS2.1 9.5.1 rule 7 says:
+
+    A left-floating box that has another left-floating box to its left
+    may not have its right outer edge to the right of its containing
+    block's right edge. (Loosely: a left float may not stick out at the
+    right edge, unless it is already as far to the left as possible.) An
+    analogous rule holds for right-floating elements.
