HSTS preload list change for

Reported by, Aug 10 2015

Issue description

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.130 Safari/537.36

Steps to reproduce the problem:
We inadvertently broke some of our customers websites hosted being accessed as third level subdomains of by getting listed in the HSTS preload list. 

For example:

We looked into SSL certificate that support multiple levels (i.e. *.*, and while this looks to conform to RFC 2818, it doesn't look like any major browsers (including Chrome) will validate them.

What is the expected behavior?
Load third level domains requested over HTTP over HTTP for 

If possible: we'd like to maintain our HSTS entry for our top level domain i.e. include_subdomains = false. is currently listed on line 2435 of the following file:

What went wrong?
We jumped the gun getting listed in the HSTS list without understanding the consequences to our third level domains. Sorry guys.

Did this work before? N/A

I think lgarron is managing the HSTS preload these days.
Hi lgarron, Let me know if there's any other details I can provide to get this change applied to the chromium source. I know it takes a while for these to go through the proper release channels.

Thanks for the poke. 

agl@: The only preloaded entries with `"include_subdomains": false` are the Yahoo! bunch.
Would you be alright with changing an individual domain to "include_subdomains": false in-place, or would you prefer to remove it completely?

Tweaking the include_subdomains flag is fine in this case.
