Is this a new bug introduced with M67 and please provide testing information. Thanks.

This is introduced by:
https://bugs.chromium.org/p/chromium/issues/detail?id=776476

Bug found by first party consumer that permission is not granted after reboot.
Tested with crafted test app, that permission can persist after reboot. 

Note that cindyb@ is shadowing M67.  I see the bug sans the cc per a search :-). 

This appears to be a fairly old issue (M64).   Limiting merges for M67 regressions at this point.  

Is #5 a confirmed test pass?  Not clear.

Re#7 yeah. This is a corner case fix.

I'm going to reject since due to the age.  Better to limit M67 changes at this point.  Re-request if that escalates.

This feature currently has very limit impact to ChromeOS since it's hidden API. 

And only one of our first party developer are using it in M67. But it's important to their launch schedule.

Please re-evaluate.

FYI, b/78231419 was hidden from TPMs due to incorrect hotlist usaged; I commented as such on that bug.

See comments on that bug re: testing
