-//   'DxoPivotGridFieldChooserTextsComponent', 'DxoPivotGridFieldChooserTextsComponent'.
-// Both modules generate their own nested-options component for that tag name, and combining
-// them in one standalone component's imports puts both in scope at once. Needs a real fix in
-// devextreme-angular's generated wrappers (or dropping one of the two imports if one turns out
-// to be redundant here) rather than a demo-side workaround.
