current_region (Ctrl+A, and the range that sort, filter, AutoSum,
tables and Get Data use when one cell is selected) grew the region one
ring of cells per step and stopped after 10,000 steps, rescanning every
cell of the ring each time. With 20,000 rows of data and one cell
selected, data.sortDescending sorted only the first 10,001 rows and
left the rest as they were; a 100,000-row region took 30 s and was cut
at row 10,001.
It now grows one side at a time while the line next to that side has
data (diagonals included), checking only the cells of that line, with
no step limit.
jump() searched for the next filled cell by stepping (dr, dc); with
neither set, the step never moved, so selection.move {"jump":true}
from a blank cell of a sheet with content looped forever (found with
an agent call that left out dr and dc). It now returns the cell it
started from.
