Thanks you!

Having the permission prompt obscured in Linux fullscreen is not desired, this is a regression.

We also fail a DCHECK now if a hosted app in its own window opens a permission prompt:

Fix permission prompt anchoring in fullscreen when UI is hidden

This CL fixes a regression caused by https://chromium-review.googlesource.com/1004886
where permission prompts would appear partially off screen in full screen mode
on platforms where we hide the Chrome UI.

Before:
https://bugs.chromium.org/p/chromium/issues/attachment?aid=334665&signed_aid=cQIe_b4bfUZn8i-akRK_ZQ==&inline=1

After:
https://bugs.chromium.org/p/chromium/issues/attachment?aid=334829&signed_aid=cXhOlJe-_oibvrzmLtL4Bw==&inline=1

This also fixes the DCHECK in GetPageInfoAnchorRect() to be relative to
GetPageInfoAnchorView() rather than copy pasting its bail out condition.
