Fenix: [Bug] "scroll to hide toolbar" option does not work (with bottom toolbar)

[cadeyrn]

Steps to reproduce

1. Make sure you have the bottom toolbar enabled
2. Disable the new "Scroll to hide toolbar" option

Expected behavior

Static toolbar.

Actual behavior

Still a dynamic toolbar. Since the other new options "Swipe toolbar sideways to switch tabs" and "Pull to refresh" both works I guess the "Scroll to hide toolbar" option is also supposed to work.

With the toolbar on top the option works.

Issue on Youtube Mobile page (m.youtube.com) when Toolbar on Top and Scroll to hide toolbar is off. Youtube Bottom Toolbar will float above what suppose to be Firefox Bottom Toolbar.

@MicroBeast Please open a separate issue for other problems with the toolbar.
