Optgroup is a nest-able control for creating a heriarchy of grouped options
within a SELECT element. When one optgroup is nested within another one, after
the closing optgroup tag, the list appears to be out-dented.
I see this too (Linux build 2001-05-07-08).

OPTGROUP isn't nestable, according to the HTML 4.01 recommendation, so this
would be invalid anyway. However, the browser should ignore invalid code, not go
nuts. I'll try to get a testcase made to demonstrate the described situation.
Attached file OPTGROUP testcase
The results are reasonable: In 2001060409 Win98, the browser is expecting users
to leave their OPTGROUP tags open, so when it finds an OPTGROUP tag before the
closing /OPTGROUP, it tries to start a new OPTGROUP as though the previous has
ended, and disregards the extra closing tag later on. The recommendation does
require an end tag, so it wouldn't be unreasonable to go ahead and support
nested OPTGROUPS rather than behave this way, but that would be going above and
beyond when at the same time Netscape's having enough trouble keeping the
program from crashing and losing data.

You can go ahead and change the OS to All, though.

It makes you wonder what happened to proposals like this:

Nested optgroups aren't allowed, and their contents are supposed to just be ignored, which will be fixed with bug 1214164.
