JS editor won’t publish pasted content

Hello,

I have implemented free version of this plugin on my website. everything works fine expcept when someone copy and paste content into form it will not recognise it unless soomething is manually typed into form. It seems a problem because nature of my website is that many users will just copy paste content and not mannualy type it.
I tried Markdown editor but it is very complicated for ordinary users.

Can you provide a solution.

Thanks
