When I was looking at your skin this morning I was confusing this thread with another one and was looking for a problem with the edit links (in the other thread the edit links were hidden by css ie color and background color being the same makes things invisible) but I realized just now that other than the Chrome problem (which I could not replicate) you mentioned a problem about the icons in the ordered list so I took another look and figured out what was causing the problem.
In one of our core css files we need to override those icons otherwise they appear in places we don't want them in the admin menu and other unordered lists but by mistake some artisteer specific selectors were in our core css file located at:
/Data/style/adminmenu/style.css
the problem part is like this:
div.mojo-tabs ul > li::before, .art-post ul > li::before, .art-textblock ul > li::before,
div.adminmenu ul.simplelist > li::before, .art-post ul > li::before, .art-textblock ul > li::before {
content: ''; display:block;}
and it needs to be replaced with this:
div.mojo-tabs ul > li::before,
div.adminmenu ul.simplelist > li::before {
content: ''; display:block;}
that will make the icons appear in your content in undoredered lists
After making css changes go to Administration > Advanced Tools > Design Tools > Cache Tool and click the button to reset the skin guid.
I'm making the same change in my copy to fix this for the next release.
Best,
Joe
