When the meta viewport tag is set to content=”width=device-width,initial-scale=1”, or any value that allows user-scaling, changing the device to landscape orientation causes the page to scale larger than 1.0. As a result, a portion of the page is cropped off the right, and the user must double-tap (sometimes more than once) to get the page to zoom properly into view.
Yes, it’s the old orientation and scale bug in Mobile Safari.
I’m pleased to report that as of iOS version 6, this bug seems to have finally been squashed. Hallelujah!
Stand down, hackers, stand down. This bug has been taken care of.
