Large dropdown menus (off expected location)
This is a bug in Google Chrome or a compatibility issue between Google Chrome and macOS Sierra 10.12.4. 

Safari uses the WebKit engine and Firefox uses the Gecko engine to render web pages, and I've tested each and they load the hiking-biking page you reference just fine in macOS Sierra 10.12.4.

I also tested Chrome visiting the same page and it worked fine in El Capitan but not macOS Sierra 10.12.4.

I'd suggest you send feedback via the Help > Report an issue option.
