When I scroll the page and click the arrow under the two lines, the menu position is bugged. (only smartphone)
Browser: Chrome
Menu: Submenu
incorrectly: I think it's designed not to scroll
See below video, duplicatable with Chrome Devtools.
To trigger, scroll page such that the submenu expander is the top visible element on the page.
