Wordsearch cursor not ligned

Hi all,

I have been testing Wordsearch and noticed that when the shortcode is placed in a drop-down/accordion the cursor doesn't highlight words correctly until the screen is refreshed.

I am using SNORDIAN's H5P Resize Pulse to be able to add H5P shortcode to accordions. However, when the shortcode is added anywhere else where SNORDIAN's is required, the puzzle functions correctly. 

Has anyone encountered this or have a workaround to it.

Many thanks

Regards

Gavin
