thank’s for your contribution. currently i can’t reproduce this behavior using chrome 30.0.1599.66 with EnlighterJS 1.6.
it looks like a influence of your theme’s css. could you please provide me a like to a test page ? i will do some investigations and try to harden the Enlighter css code. Another option is that you take a look into your css and remove margin/padding/indents from <li> and <ul> elements
