Christopher, I have been having this problem on my iPad 4(OSX9.3.4) only, using Safari, for more than 6 months. Of course, my 2 PCs(Win10, Firefox) don't do this, nor does my wife's iPhone 6Plus (Safari), or her iPad2 Mini(Safari). Only on my iPad4. I have searched several times, tried all of the suggestions, and none of them have worked. This issue only occurs on Yahoo pages, no other webpages. In fact, it only seems to occur on Yahoo news webpages. It doesn't happen if I'm looking at Yahoo sports, or their support community pages (searching for answers to this issue). It is particularly vexing to me when I am near the end of a news article or looking at the comments. I have concluded that it must be something in Yahoo's news page code versus some configuration on our particular devices. I don't think that we will find a solution to this issue because I don't think that it is common enough to garner enough attention. I use other websites to read news now. That's the only solution that has worked for me, but it is a poor solution, IMHO.
