Assertion:
Netscape 6 Beta 1 had a bug with MENU lists: Unless LI elements in the menu list were explicitly closed (they should be optional), the menu indentation level was maintained for the rest of the document. This behavior was fixed in 6.0 Beta 2.

Basic MENU list with closing LI elements:
filler text
  • LI item 1
  • LI item 2
  • LI item 3
  • filler text

    Basic MENU list with no closing LI elements:
    filler text
  • LI item 1
  • LI item 2
  • LI item 3
  • filler text
