Comment (by jaspermdegroot):

 Replying to @azaozz, @johnbillion, and @joemcgill:

 Good point about page caching. So let's indeed not do something for iOS(8)
 specific.

 Just to put things in perspective: 1% of ~3.5 billion internet users is
 still 35 million people. It's a bigger market share than whole Windows
 Phone. These are probably mostly people that have an iThing that can't be
 upgraded to iOS9 so I think the number won't decrease very fast either. If
 it was about iOS8 users not benefiting from an enhancement it would be a
 different story, but here we are breaking something that used to be ok. So
 I really think we should fix this.

 In 35030.3.patch: Instead of using two arrays, prepend the src image to
 the `$sources` array. Compared to @azaozz his patch I used the `+`
 operator instead `array_merge()` because of the difference in how
 duplicate keys are handled.
