-/**
- * Helper function to swap the text of a TranslationItem
- * between its original and translated states.
- * How it works:
- *
- * The function iterates through the target array (either the `original` or
- * `translation` array from the TranslationItem), while also keeping a pointer
- * to a current position in the child nodes from the actual DOM node that we
- * are modifying. This pointer is moved forward after each item of the array
- * is translated. If, at any given time, the pointer doesn't match the expected
- * node that was supposed to be seen, it means that the original and translated
- * contents have a different ordering, and thus we need to adjust that.
- *
- * A full example of the reordering process, swapping from Original to
- * Translation:
- *
- *    Original (en): <div>I <em>miss</em> <b>you</b></div>
- *
- * Translation (fr): <div><b>Tu</b> me <em>manques</em></div>
- *
- * Step 1:
- *   pointer points to firstChild of the DOM node, textnode "I "
- *   first item in item.translation is [object TranslationItem <b>]
- *
- *   pointer does not match the expected element, <b>. So let's move <b> to the
- *   pointer position.
- *
- *   Current state of the DOM:
- *     <div><b>you</b>I <em>miss</em> </div>
- *
- * Step 2:
- *   pointer moves forward to nextSibling, textnode "I " again.
- *   second item in item.translation is the string " me "
- *
- *   pointer points to a text node, and we were expecting a text node. Match!
- *   just replace the text content.
- *
- *   Current state of the DOM:
- *     <div><b>you</b> me <em>miss</em> </div>
- *
- * Step 3:
- *   pointer moves forward to nextSibling, <em>miss</em>
- *   third item in item.translation is [object TranslationItem <em>]
- *
- *   pointer points to the expected node. Match! Nothing to do.
- *
- * Step 4:
- *   all items in this item.translation were transformed. The remaining
- *   text nodes are cleared to "", and domNode.normalize() removes them.
- *
- *   Current state of the DOM:
- *     <div><b>you</b> me <em>miss</em></div>
- *
- * Further steps:
- *   After that, the function will visit the child items (from the visitStack),
- *   and the text inside the <b> and <em> nodes will be swapped as well,
- *   yielding the final result:
- *
- *     <div><b>Tu</b> me <em>manques</em></div>
- *
- *
- * @param item     A TranslationItem object
- * @param target   A string that is either "translation"
- *                 or "original".

-    // will be necessary to produce the correct translation.

-    // this better aligns the resulting translation with the DOM content of the
