If the user-agent does not claim to support the :hover pseudo-class (e.g. the pointing device cannot detect hovering), then SKIP this test.
If the user-agent does not allow scrolling the document while leaving the pointer in the same position relative to the viewport, then SKIP this test.
Ensure that this document is scrolled all the way to the top.
Hover the pointer device over the button below.
If the button is not blue, then the test result is FAILURE.
Scroll this document down while not moving the pointer at all, until the pointer no longer touches the button. For example, on a traditional desktop or laptop computer, keep the mouse perfectly still and do one of the following:
Press the "Page Down" key on the keyboard.
Press the "↓" key on the keyboard.
Roll the mouse's scrollwheel.
Perform a "scroll down" gesture on the trackpad
If the button is blue, then the test result is FAILURE. If the button is white, then the test result is SUCCESS.
