Steps to reproduce

1. With bundled MTK2 (M6.2.10)
2. Enable old pages app
3.  Open old pages app via findbar (or refresh browser to reveal the old pages app in the applauncher)
4. Add MTK2 basic page (not MTK1 which is marked as deprecated).

Expected results

I cannot use MTK2 templates as those are not compatible with the old pages app.

Actual results

I can use MTK templates but opening their dialogs fails.

Workaround

Use deprecated MTK1 templates.

Development notes

Templates with new framework dialogs can be filtered and not shown in template selector.
