This issue only seems to affect the demo site not when I have downloaded the v9 files to local
Several menu types do not work:
Start with npm run dev and select the Horizontal menu style.
The menu shows but if I click the menu dropdown icon there is a brief flicker but no menu items are shown.
The browser is an up to date one Chrome Version 114.0.5735.248 (Official Build) (x86_64)
I am particularly interested getting the horizontal menu working.
