<pre>visiblePositionForTextMarkerData transforms TextMarkerData into a VisiblePosition. As a sanity check it compares the node and offset values of the position returned by createLegacyEditingPosition() with the deepEquivalent() of the resulting VisiblePosition. This doesn't account for canonicalization of the position via Position::upstream and Position::downstream causing the position to incorrectly be considered invalid.</pre>
