HTML formatting issues when switching between editor tabs

I was finally able to get this fixed after some more debugging.
I had previously disabled TinyMCE emojis which is what was causing the issue.

After removing this code from functions.php the editor started working as it normally does.

function disable_emojis() {
    add_filter( 'tiny_mce_plugins', 'disable_emojis_tinymce' );
}
add_action( 'init', 'disable_emojis' );
