Actually, the expected results would be:
1. (1) This is the first item.
2. (2) This is the second item.
3. (3) This is the third item.

Because the LI still has display type 'list-item'.

This isn't a failure of 'display: marker' so much as the fact that CSS2 counters
aren't implemented (and not promised for this release).

Perhaps, but maybe display: list-item should be considered to have an implicit
:before with display: marker, overridden by any other :before.

No. see the CSS2 spec 12.6.1.
( http://www.w3.org/TR/REC-CSS2/generate.html#markers )

|When the 'display' property has the value 'marker' for content generated by an
|element with 'display: list-item', a marker box generated for ':before'
|replaces the normal list item marker.

 If counters aren't implemented, the entire declaration (consists property and
value) should be ignored. Therofore, the expected results would be:

>1. This is the first item.
>2. This is the second item.
>3. This is the third item.

CSS2 support is not planned for 5.0. While we have limited CSS2 support, and we
may actually do this before we ship -- it's not technically a bug.

I'll set this to Verified/Later in case we can get to it before ship. ;-)
