Video showing current horizontal scrolling in RTL
DESCRIPTION
When using Okular in a Right-to-Left (RTL) language interface such as Arabic,
horizontal scrolling and boundary drag-scrolling inside a zoomed-in document
operate in reverse. Moving the cursor to the left moves the view to the right,
and vice versa.
STEPS TO REPRODUCE
1. 1. run okluar with Arabic locale, from Konsole:
LANGUAGE=ar_OM:ar LC_ALL=ar_OM.UTF-8 okular
2. Open any pdf file and zoom in to 200% (or till the horizontal scroll bar
appears)
3. Scroll to left and notice the view direction
OBSERVED RESULT
Scrolling left shifts the document view to the right.
EXPECTED RESULT
Scrolling left shifts the viewport left to reveal content on the left side of
the page.
