Note: This only applies to Chrome-dev and Chromium. If you are on the regular Google Chrome, you are completely unaffected.
There is a bug in the current Webkit (Chrome’s rendering engine) that causes all rotated images to not be clickable. This version has a work-around to fix the dual arrow’s bottom button. Unfortunately, the Flip mode is not fixed and you will not be able to jump down to the bottom until the bug is fixed, hopefully soon!
When the bug is fixed, the work-around will be removed and all shall resume as normal :)
