This is expected, according to the comment here
https://cs.chromium.org/chromium/src/chrome/browser/ui/browser_command_controller.cc?rcl=baf611e16997ded33cae4f4b8aa691fcef8fabec&l=176, intercepting the function keys on ChromeOS is disallowed.

Thanks, Zijie, It looks like the change that introduced that predates your work to allow browser shortcuts to be intercepted in full-screen mode, so I think this bug is still valid.
