Syntax Error in the plugin

Hello. One of my website was crashed this morning. I saw that during the night, an update were made on this plugin to version 4.9.19
I watched on my error log and saw: PHP Parse error: syntax error, unexpected ‘)’ in *******************/wordpress/wp-content/plugins/premium-addons-for-elementor/includes/addons-integration.php on line 634, referer: **************

I checked and on these lines (628 to 634), i had:

wp_register_script(
			'pa-headroom',
			PREMIUM_ADDONS_URL . 'assets/frontend/' . $dir . '/headroom' . $suffix . '.js',
			array( 'jquery' ),
			PREMIUM_ADDONS_VERSION,
			// true
		);

The // true made my website crash. After PREMIUM_ADDONS_VERSION, there is a ‘,’ so the program is waiting another arg. With ‘// true’, it doesnt get another parameter and crash the website. i removed the ‘//’ and saved, my website was functional again.
Is this problem something that only happened to me ?

I deactivated the auto update for this plugin. Can you assure me that this little syntax error will not be in the next version of the plugin ?

Thank you for your time.
