Description Laura David Hurka 2019-06-09 18:01:30 UTC 
SUMMARY
The Magnifier tool can scroll the document, if dragged against the view edges.
However, this scrolling does not stop.

STEPS TO REPRODUCE
1. Open a document with many pages.
2. Select the Magnifier tool (e. g. Ctrl+6).
3. Click and hold near the bottom edge of the view, to see it magnified.

OBSERVED RESULT
Document scrolls like expected.

STEPS TO REPRODUCE
4. Move the magnifier to the middle of the view.

OBSERVED RESULD
Document continues to scroll, so you can’t read anything.

EXPECTED RESULT
Document scrolls only when the magnifier is dragged against the edges of the view.

KDE Neon 5.15

BONUS
Make the Okular window really small. Then, scrolling goes unpredictably in various directions.
