When using an the In-Place control with type "RTE". The RTE toolbar fails to render correctly if any value is specified for popupSettings.model.afterOpen.
The toolbar is rendered but where there are more items than can fit in one row the expand button is added. Clicking on the expand button expands the toolbar to an additional row but there is no content in the second row.
The effect can be seen in this js fiddle - https://jsfiddle.net/5jraw8sq/2/
In the fiddle, comment out the afterOpen item in the control definition to have the toolbar render correctly.
This happens even when afterOpen is specified but no value is set. e.g. afterOpen: undefined
Please advise if there is a workaround for this issue.
