Bugs in content types

While testing the: https://h5p.org/column#example=34129

I notice the ‘Column’ library issues completion event every time you interact with ‘Drag and Drop’ — provided this is the last activity you interact with (going from top to bottom). 

If the ‘Drag and Drop’ is NOT a last activity (e.g., going from bottom to top) the issue is not present. 

Library name: Column
Library version: 1.12.0


Fix could be at h5p-column.js

Hi all,

When building a drag and drop, many users at our org find that the finished product prompts learners which drop zone is correct, by highlighting the correct box with a dotted line. It also only allows the learner to place it on the correct spot, as opposed to fully labelling the diagram, then checking to see if they are correct.  I have seen other drag and drops not have these issues - what might we be doing wrong?  I've included an example. 

Running Drupal H5P module.  Everything was working without issue until today when I started seeing the following errors.   Drupal 8.8.5 with version 8.x-1.0-rc17 of the H5P module.
