TEST=Launch chromium and trigger an infobar.  Enter fullscreen, ensure that presentation mode is off (the UI is always visible), then Cmd-F to trigger find in page.  Findbar should be visible even when the overlay is open.

LGTM if you've verified that infobars still look OK.

This doesn't work with your new infobars.  I think the fix is to change the test
from isFullscreen to inPresentationMode.  Will upload new diffs when I get a
chance.

Back to you.  Switching the test to presentation mode seems to fix all the
problems, and actually makes sense as a fix.

LGTM
