Not a bug, but a fact of life. It must generate the OFFSET number
of rows and continue to generated the next LIMIT rows (or continue
processing until there are no rows). If matching rows are scarce
after OFFSET rows are found, it can take a while to get enough or
to find out that LIMIT rows don't exist.
Personally, I never use OFFSET and LIMIT for pagination; there are
better ways for most situations.
