__Current behavior before commit:__ If there is no link in one of the hamburger menu element, `el.querySelector` will return `null` and an error will be thrown when it tries to access `classList`. __Description of the fix:__ Add a check on `itemLink` and `navLink` before accessing `classList`. __To reproduce:__ 1. Add 2 pages with long names to the website, make sure they are included in the navbar 1. Open Website Editor 1. Click on the navbar 1. In the **CUSTOMIZE** tab, inside the **Navbar** section, change **Mobile Menu** to `Off-Canvas` 1. Set **Mobile Menu > Off-Canvas Logo** to `Text` 1. Reduce the width of the page *just enough* so that the hamburger menu appears instead of the navbar menus only when the web editor is on 1. Click on the hamburger menu, and remove the link of the "My Website" text at the bottom 1. Exit the Web Editor ([Video](https://watch.screencastify.com/v/dWI3g6NnT5uRcp2KmBOO)) opw-3443200 closes odoo/odoo#131373 X-original-commit: 5b9eb3a1d016a16d395e9888ccd1606543eb99e2 Signed-off-by: Luca Vitali (luvi) <luvi@odoo.com>
