Use of expand operator results in syntax error

Version: 2.7.3

Bug Description

When attempting to use the (expand) operator to pass array of parameters to {control}, it results in syntax error.

Steps To Reproduce

{var $args = ["label" => "Název"]}
{control myControl, (expand) $args}

Will cause synax error on line 89:

<?php
86:                    $args = ["label" => "Název"];
87:                    /* line 25 */ $_tmp = $this->global->uiControl->getComponent("myControl");
88:                    if ($_tmp instanceof Nette\Application\UI\IRenderable) $_tmp->redrawControl(null, false);
89:                    $_tmp->render(rray_merge([], $args, []);
?>

Expected Behavior

Should be equivalent to {control myControl, label => "Název"}
