    I’ve not been able to replicate this issue. I wonder if its specific to your set up (i.e. plugins/themes).

    Are able to determine what the call trace is that leads to this warning? You can do that by adding these lines just before line 1500 in wp-includes/formatting.php (source: https://github.com/WordPress/WordPress/blob/4.6.1/wp-includes/formatting.php#L1500).

    
if ( is_array( $string ) ) {
    error_log( wp_debug_backtrace_summary() );
}

    Only do that if you’re comfortable editing WordPress’ source files, and please don’t do it on a live site!

    The other two warnings are caused by the first.
