Custom Widgets and Tab index

We have a form with several custom widgets from the app store. They seem not to have a tab index. This used to be a normal property for Mendix 3. Has this not been implemented yet for Mendix 4? Any idea how we can change or add the tab index for the custom widgets without waiting for a new Mendix version?

The possibility to edit the tab index for custom widgets was mistakenly hidden in version 4.0.0. This will be fixed as soon as possible in an upcoming release. We apologize for the inconvenience.

Please note that tab index values for existing custom widgets converted from version 3 are retained in the model; they are just not visible or editable for now.
