When authoring content in the Pages app or other content apps, switching the authoring language causes the open dialog's tabs to lose their label and revert to using name.

To reproduce in the demo environment, open the homepage of Magnolia Travels and attempt to add a "Text and image" component. The two tabs will be labelled Text and Image.

Using the language switch, switch to German. The tabs will now be labelled tabText and tabImage, their names in the dialog definition.

Reverting to English does not restore the labels.
