Elementor\Controls_Stack->is_control_visible - What does it do?

[realfabiangless]

Hello,

I would like to understand what this function does in Elementor:

public function is_control_visible( $control, $values = null ) (its from Elementor\Controls_Stack->is_control_visible)

The comments in the code are

/**
* Whether the control is visible or not.
*
* Used to determine whether the control is visible or not.
*
* @SInCE 1.4.0
* @access public
*
* @param array $control The control.
* @param array $values Optional. Condition values. Default is null.
*
* @return bool Whether the control is visible.
*/

For our page, this function takes 10 seconds to load, it is really critical. Hope someone can explain what it does and what could influence it to take that long.
