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.

Shell activeShell = e.display.getActiveShell();
								if (activeShell == getShell()
										|| (infoPopup != null && infoPopup
												.getShell() == activeShell)) {
									return;
								}
								/*
								 * System.out.println(e);
								 * System.out.println(e.display.getFocusControl());
								 * System.out.println(e.display.getActiveShell());
								 */
								close();
