How to put the plugin out of focus when i click a element outside the editor?

[MiniJude]

Hi, thank you for providing this plug-in for our convenience!

I found that when i click on a image and then click on a input and press delete, the image will be delete too.
So can you teach me how to put the plugin out of focus when i click a element outside the editor.

this is a demo
