Aliaksandr Kalenik 0fcd8c0bfa LibWeb: Fix pseudo-element scroll offset leaking to generating element ...

In Element::set_scroll_offset(), when setting a pseudo-element's
scroll offset, the code was also incorrectly setting the generating
element's own m_scroll_offset. Added an else branch so only the
pseudo-element's offset is set.

Also adds a ref test for scrollable pseudo-elements to prevent
regression. The test scrolls a ::before pseudo-element via wheel
event and verifies the content scrolls correctly.
