Not sure whether this is ContentEditable, DataModel or LinearModel.

When pasting italicised text (from elsewhere on the same page) into an already italicised sentence we currently close, re-open, close, re-open that annotation.

Steps to reproduce problem:

• start with: <p><i>Original text here.</i></p><p><i>Something else there.</i></p>
• select "else"
• copy
• select "text"
• paste to replace
• end state: <p class="ve-ce-branchNode"><i class="ve-ce-TextStyleAnnotation ve-ce-TextStyleItalicAnnotation">Original </i><i class="ve-ce-TextStyleAnnotation ve-ce-TextStyleItalicAnnotation">else</i><i class="ve-ce-TextStyleAnnotation ve-ce-TextStyleItalicAnnotation"> here.</i></p>

Now this wouldn't be a major issue (merely inefficient) if it weren't for bug 48194 in Parsoid.
