Google Chrome	71.0.3567.0 (Official Build) dev (64-bit)
Firmware Version Google_Caroline.7820.384.0

Steps to repro:
# Launch the Chrome Remote Desktop app
# Tab through entire app 
Expected: able to reach the "Options" menu and other buttons on the right 
Actual: not able to put focus on the buttons on the menu, see screenshot

Some of the buttons have keyboard shortcuts that replace their functionality such as close window but most do not.
