Starting with an ol with a start=5 and five lis, inserting, appending, or deleting an li or changing the start attribute causes one of the item numbers to jump out of alignment with the other numbering.  The li content stays correctly aligned.

For example, inserting a new li before the first causes item numbered 10 to lose the gutter space between number dot and content.  Conversely, some operations cause item numbers to appear well left of the normal dot alignment.

I didn't check if the start attr value being set, or being set to something other than 1, was circumstantial.

Noticed this in 3.0.4 Mac, 3.0.4 XP, and 3.1 XP but the misalignment was different.  XP tests done under VMWare.

Reproducible: Always

Steps to Reproduce:
The included URL is a pared down test case, but...

1. Include in markup an ol containing five lis and start attribute set to 5
2. in a <script> tag, create and insert a new li before the first child of the ol

Similar actions for removing an li and changing the start attribute.
