To replicate the bug:
Make sure you're on the HFP-225-wysiwyg-editor-arrow-key-movement of h5p-drag-n-bar
Create a text box in CP, note that it can be moved using the arrow keys
Switch to the drag and drop editor and create a text element
Switch back to CP editor, create and try to move a text box. Note that it can't be moved.
The editor remembers focused elements when changing content type, meaning that it piles up with multiple focused elements and gets confused about what to handle.
This happens somethimes opening editor for sub content, example DnD inside CP. CP elements are still in focus while DnD editor is active.
This issue blocks
The editor should not remember focused element on changing content type.
