Bug#711261: okular: Alt-Scroll for horizontal scroll behaves differently at top and bottom of page

[Zachary Palmer <zep_debbug@bahj.com>]

Package: okular
Version: 4:4.8.4-3
Severity: minor

Dear Maintainer,

I was happy to discover that okular can horizontally scroll when one is holding
the Alt key.  There seems to be a minor bug associated with this behavior,
though.  When *not* in continuous view mode, when viewing single pages, and when
the vertical scroll bar is locked to the top position (and the view is at the
very top of a page), pressing Alt and scrolling up (which intends to scroll
left) causes the document to scroll up to the bottom of the previous page.  This
is not a feature designed to support document reading, as this scroll-up
behavior occurs regardless of the position of the horizontal scroll bar (and the
horizontal position of the document is unchanged).  Likewise, attempting to
scroll right when viewing the very bottom of a page scrolls down instead.

This bug is marked minor because it is easy to work around as a user: just
scroll a little away from the page boundary and horizontal scrolling works as
desired.  It's a bit disorienting, though.  :)
