Inserting new line right before tag that has an inline editor below it causes inline editor to close

[tvoliter]

1. Create a project with the following html and css files:

<div id="wrapper">
    <div id="header">
    </div>
</div>

#header {
    width: 980px;
    margin: 80px auto 0 auto;
    position: relative;
}

1. In the html file click "header" on line Fleshed out overall UI layout #2 and bring up the inline editor
2. Put the cursor right before "<div" on line Fleshed out overall UI layout #2 and press the enter key

Result:
The inline editor is closed.

Expected
Since the div tag is still intact the editor should remain open.

I found that many other types of edits that do work including:
a. inserting newline at the very beginning of line #2
b. inserting a newline in the middle of the div tag
c. inserting a newline anywhere above line #2

Turns out this is a bug in the CodeMirror bookmark mechanism. Fixed in pull request https://github.com/adobe/CodeMirror2/pull/35 -- once that's pulled I'll submit it to Marijn as well since it's easily separable from our other CM changes.
