Bug 132798 [Field Assist] - Pressing Backspace at offset 0 should not reload field assist popup
N20060322-0010. After migrating the Find/Replace dialog to the new field assist support I found the following blooper: pressing the Backspace key at offset 0 reloads the field assist popup. Test Case: 1. in a text editor press Ctrl+F 2. enable regex search 3. in the Find filed press Ctrl+Space 4. continuously press Backspace ==> each time the proposal list is reloaded.

					scrollbarClicked = false;
					/*
					 * Ignore this event if it's only happening because focus is
					 * moving between the popup shells, their controls, or a
					 * scrollbar. Do this in an async since the focus is not
					 * actually switched when this event is received.
