Page shifts down after first tag is added

[hgilani]

As soon as first tag is added all the elements defined after the tag field shift down slightly. This can be observed in the demo page as well.

tagit-simple-grey.css has following CSS which seems to be causing this issue

ul.tagit li.tagit-choice {
    background-color: #f7f7f7;
    border: 1px solid #f2f2f2;
    padding: 2px 13px 3px 4px;
}

ul.tagit li.tagit-new {
    padding: 2px 4px 3px;
    padding: 2px 4px 1px;
    padding: 2px 4px 1px 0;
}

If the CSS rules are changed as following then this problem seems to go away.

ul.tagit li.tagit-choice {
    background-color: #f7f7f7;
    border: 1px solid #f2f2f2;
    padding: 2px 13px 1px 4px;
}

ul.tagit li.tagit-new {
    padding: 2px 4px 3px;
}

Also, I am noticing these CSS rules are defined differently for other theme colors.
