Use bottom stage bounds in determineHandlePosition.

Fixes an issue where bottom split task still would get a status bar
input layer due to determineHandlePosition never actually calculating a
position below the status bar. This resulted in top-split handles
opening the handle menu on bottom-split tasks.
