Revert of Center permission bubble if location bar is hidden in MacOS.

Revert of Center permission bubble if location bar is hidden in MacOS. (patchset #19 id:360001 of https://codereview.chromium.org/986333006/)

Reason for revert:
I believe this is causing the Mac ASan 64 Tests (1) bot to fail:

==56836==ERROR: AddressSanitizer: stack-use-after-return on address 0x00011a38dc78 at pc 0x000104e8028f bp 0x7fff5f6e5600 sp 0x7fff5f6e55f8
