> “ROWS between 10 preceding and 2 preceding” is not handled correctly.
> Underlying error: Window range invalid, start boundary is greater than end
> boundary: window(start=range(10 PRECEDING), end=range(2 PRECEDING))
> If I change it to “2 preceding and 10 preceding”, the syntax works but the
> results are 0 of course.
> Reason for the function: during analysis, it is sometimes desired to design
> the window to filter the most recent events, in the case of the events'
> responses are not available yet. There is a workaround for this, but it is
> better/more proper to fix the bug.
