ListView.EditEvent.getIndex() does not return the correct index

FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
ListView.setOnEditCancel is called with an EventHandler, that gets a ListView.EditEvent as argument.

That EditEvent has a function called `getIndex()`, which just returns the ListView's currently edited index, while the doc says, it would give the index of the edited field.

If `onEditCancle` gets invoked because you edit a cell and cancel that by editing another field, EditEvent.getIndex() actually returns the index of the field, that cancelled the edit, and not the field that got cancelled

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the provided source code and click the buttons.

Since this is a JavaFX problem, I couldn't quite figure out how to make a test case out of it. Sorry.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The output displays the index of the field, that had editing cancelled
ACTUAL -
The output displays the index of the field, that cancelled editing for the other

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
call `listView.getSelectionModel().select(index)` before `listView.edit(index)`
