Internet Explorer ordered list non-incrementing list item

This bug is already documented at QuirksMode. Basically, instead of normal list-item increment: 1, 2, 3 and so on, IE 6 renders 1, 1, 1,…

It’s sometimes triggered by setting any value for an ol’s width property. Read more about it and see test pages at QuirksMode.

Setting and overriding list-style property rules for a list-item does the same mess. For example:

li    { list-style: none; }
ol li { list-style: outside decimal; }

would trigger this bug.

The workaround is more than obvious – list-style property should be set only for list items in unordered lists.
