LR-PREF-GENERAL: the long-path test scrolls to the watched folder before reading it

The row is at the foot of Import. With more sections above it (another
pull request adds one) it is below the fold of the 640 pt page, and a row
that is not drawn has no text to read: the test failed for the page's
length, not for the path.
