Freeze break request for libsoup

[mcatanzaro gnome org]

Hi,

A couple weeks ago, I pushed a patch to make the third-party cookie 
policy in libsoup less strict [1]. I asked Claudio to revert it 
immediately before the code freeze because Ting-Wei found a regression: 
it accidentally caused certain cookies  (cookies with the domain 
property set to a value with a leading period) to be blocked, which was 
not intended.

I've fixed the regression and would like to re-land the patch now. This 
fixes notifications on google.com, so it is a major fix. I'll give 
myself the first approval... will anybody second it?

Thanks,

Michael
