Plugin “looses” html tags attributes

Plugin unsystematically “looses” some html tags attributes that acceptable on a post/page screen. For example, it looses “style” for <div> and <table> tags but allows them for <p> and even for <iframe>, but looses class and loading for <iframe> and so on.

I’m sorry but this plugin’s behavior makes using it extremely unreliable.

All these atts are not loosing on post/pages screens!!!

As the plugin designed to to used from admin panel, probably it’s unreasonable to use function wp_kses_post in line 13 of tabs-save-data.php at all or it should be arranged like in post screen.
