Description
Describe the bug
The DataGrid does not update cell values when bound to an array.
To Reproduce
Create a project that loads a row into a datagrid. Make sure the ItemsSources is set to an ObservableCollection of INotifyPropertyChanged implemented classes. Define the class with both Properties and Array Properties. Use code behind to add DataGrid columns with their appropriate bindings. Create event handlers to update both Properties and Array Properties. Notice only the Properties are updated. Array driven bindings draw the first time but do not update.
Please see the attached project to duplicate the bug. Clicking on the middle button in the application duplicates the bug.
Expected behavior
Array driven columns values should update.
