Hello,  
I noticed that JLex Review Module version 2.8.4 greatly slow down javascript on my website.
You can see it when you scroll down with scrolling wheel of the mouse,
also when you fill the booking formular,
and also when you move the mouse pointer over the main menu the reaction of the menu is slower than usual.
You can test it on my test site: https://aramis-voyage.ovh/
When I deactivate this module the problem disapear.

Thi problem happends only in Google Chrome browsers.
I've tested it on Mozilla Firefox, it works fine.

Can you please release the updated version of the JLex Review module with this problem fixed?

Best regards.
