Sorry. Been really busy but getting back to reviewing the possibility of a plugin.
For now, please try adding this to your functions.php to see if it helps.
After looking things over it seems like it was default configuration issues. The below code should enable image copy paste from clipboard, formatted copy/paste from word and excel. It’s a bit of a “nuclear option” just enabling all the wysiwyg copy/paste I could think of for now, and I’ll try to get a more refined solution here soon. Also, i’m still learning so I apologize for any crudeness to the code.
Please note this was just what I did to fix my issues with the new editor that may or may not be related to your issue. I really hope it helps your situation some though.
It’s just to enable copy/paste of images and other style elements by default. If you don’t want any style elements, paste as text should still work.
/**

function enable_tmce_paste_stylesAndImages($mceInit, $editor_id){
$mceInit['paste_data_images'] = true;
$mceInit['paste_word_valid_elements'] = "b,strong,i,em,h1,h2,p,ol,ul,li,a,span,div,font-size,br,img,table,tbody,td,tfoot,th,thead,tr,del,ins,dl,dt,dd";
$mceInit['paste_webkit_styles'] = "all";
$mceInit['paste_retain_style_properties'] = "all";
return $mceInit;
}
add_filter('tiny_mce_before_init', 'enable_tmce_paste_stylesAndImages', 1, 2);
