remove_filter( 'wpautop' ) not working completely

[RobBash]

In my functions.php I call remove_filter( 'the_content', 'wpautop' ).

After saving the output on the blog is correct so it must be stored correctly in the database, but in the editor (tinymce) it is not. I also installed the plugin TinyMCE Advanced the prevent cleanup by the editor.

I investigated the issue a bit and found out that the wpautop method is still called before the content is displayed in the editor and the double line breaks are replaced by <p>-tags, which shouldn't be after the remove_filter. I also debugged in that method to make sure the filter is removed.

I think the 'wpautop' filter is not added to the Admin Editor, so remove_filter( 'the_content', 'wpautop' ) will have no effect there anyway.

remove_filter( 'the_content', 'wpautop' ) is for the front-end online.

The editor has its own autop implementation on the JavaScript side to make editing as easy as possible.

See https://core.trac.wordpress.org/browser/tags/4.7.2/src/wp-includes/js/tinymce/plugins/wordpress/plugin.js#L13 how the editor plugin checks for its availability.
