I've been visiting SO for a while now on my Surface Pro 3. The Surface Pen is a stylus supposed to act like a mouse, so when hovering on an element, tooltips should show.
But this doesn't appear to work on Stack Exchange sites. The tooltips do show when I use my mouse, so it's not an issue with the site's rendering on my computer.
Testing:
- Pen's hover ability works on other sites.
- SO on IE11 (standard version) and Chrome were both unsuccessful with the Surface Pen.
- IE11 touch-calibrated version works with the Pen.
Perhaps, there should be added support for special touchscreen styli?
