On my iPhone 6 I'm finding the text on many web pages isn't expanding to the full screen width when I double tap it - it looks as though it's actually just using the old iPhone 5 size as the maximum (both landscape and portrait). I don't think all display this behaviour but many certainly do, for example:
This is after I've double-tapped the text to expand it.
Anyone else experiencing similar?
