horizontal line with drag the words

Recently discovered that H5P tasks look nicer when I separate the task description from the exercises with a horizontal bar.
However, doing this for tasks of the “drag the words” type, disables drop fields in the first line of exercise section. Inserting an empty line does not help, neither at the bottom of the task description nor on top of the exercise section.
Please fix this with the next “drag the words” update.
