I especially noticed this while trying to log into our beloved forums. If I expanded the page just enough to see the login popup, when the keyboard appeared, Safari would just plain quit. If I expanded it more, but not necessarily all the way, it kept running.
I've seen this on other pages too, though I can't recall 'em at the moment. Has anyone else experienced this? Is there something wrong with Safari (or my phone!), or is this just due to coding variances or other benign issue?
