The only way I could replicate this is through selecting some text, then clicking until the ? appears (which lets you search their site for the selected text) and then clicking somewhere else. The ? goes away and takes the selected text. But I think it's unintentional and do no believe they are intentionally trying to keep you from selecting text. I was able to keep the selection there.
