Fix an issue where navigationMode is reported wrong on gradle builds

Not sure why this fixes it... but it does!

Flag: EXEMPT trivial fix for sysui studio builds
Test: - build/install via sysui studio
      - get a bubble, expand it
      - swipe up on the bottom
      => observe that it tracks your finger
Bug: None
