List item-spacing wackiness

Since I’ve upgraded to 2.1.2 from 2.0.9, I’ve experienced some bizarre behavior with my lists (unordered, ordered) whenever I edit or write a post.

The first item in a list formats correctly, but the second item is oddly spaced. It’s either got an extra linefeed or loses the linefeed entirely so it runs into the first item. The lines after that will format correctly.

Even when I go into code and fix things, everything looks fine, but when I switch back to the visual editor, it’s messed up again. Switching back to code shows the problem’s returned. Sometimes the second item looks okay, but then the third item is crammed onto the back of it! There’s no sense to the error.

When I go into code and add <br />s or <p></p>to try to force the lines, the editor just tosses those away and returns to mangling my lists.

This is driving me nuts since I can’t get my lists to look right.

Thanks in advance for the help!
