Previously, the `sourceSpan` and `startSourceSpan` were the same object, which meant that you had the following situation: ``` element = <div>some content</div> sourceSpan = <div> startSourceSpan = <div> endSourceSpan = </div> ``` This made `sourceSpan` redundant and meant that if you wanted a span for the whole element including its content and closing tag, it had to be computed. Now `sourceSpan` is separated from `startSourceSpan` resulting in: ``` element = <div>some content</div> sourceSpan = <div>some content</div> startSourceSpan = <div> endSourceSpan = </div> ``` PR Close #38581
