When I point to Calc cells and scroll using the MacBook Pro trackpad or Logitech mouse scroll wheel, the window scrolls. If my mouse slips over the row labels or column labels, scrolling doesn't work. Since these labels are part of the view that will be moving out of sight when the view scrolls, their inability to scroll the view is counterintuitive.
Confirmed:18.104.22.168:OSX and latest nightly from today.
Mouse wheel or trackpad scrolling works below and above row labels (A, B, C, ...) but not when mouse is on row labels.
Indeed very counterintuitive -> NEW.
The same behavior is in Windows too
