Adding unwanted newlines when pasting

Version 1 beta 4 (https://cdn.quilljs.com/1.0.0-beta.4/quill.js)

When pasting HTML containing a header tag (e.g. <h1>) and a paragraph (<p>) an extra, unwanted, newline character is prepended in the delta object for the paragraph, resulting in an empty paragraph being inserted.

Steps for Reproduction Using jQuery. Assuming this DOM

<div id="editor"></div>
<script type="text/javascript">
var quill = null;
$(function() {
    quill = new Quill('#editor', {theme: 'snow' });
    quill.pasteHTML('<h1>headline</h1><p>Content</p>');

    console.log(JSON.stringify(quill.getContents().ops));
    // [{"insert":"headline"},{"attributes":{"header":1},"insert":"\n"},{"insert":"\nContent\n"}]

    console.log($('#editor .ql-editor').html());
    // <h1>headline</h1><p><br></p><p>Content</p>

    quill.pasteHTML($('#editor .ql-editor').html());

    console.log(JSON.stringify(quill.getContents().ops));
    // [{"insert":"headline"},{"attributes":{"header":1},"insert":"\n"},{"insert":"\n\nContent\n"}]

    console.log($('#editor .ql-editor').html());
    // <h1>headline</h1><p><br></p><p><br></p><p>Content</p>
});

Expected behavior: I’d expect the output of console.log($('#editor .ql-editor').html()); to match the input from quill.pasteHTML('<h1>headline</h1><p>Content</p>');

Actual behavior: An extra <p>&nbps;</p> tag is inserted. (Speculation:) Possibly because the header attribute is put on the newline character following the actual headline, instead of the headline itself.
