During pageload i can see the header menu shift on mobile. i have drilled it down that the shift takes place when navigation-branding.min.css is loaded. In light of Core Web Vitals, I am looking to remove this shift which takes place on page load. See below: https://www.loom.com/share/9972fb4b8e0d4644952c269995d5d169
Do you know what I can do to make sure this shift no longer appears on the website?
