TileTemplate on Popup Editing not working as it should

[Hugo01]

Package versions: devexteme version: 21.2 devextreme-vue version: 21.2

Hello. I've been facing a weird issue where the "title-template" property does not work on a DxPopup inside a DxEditing. If you use only the DxPopup component separately it works fine

Here's an example: https://codesandbox.io/s/popup-editing-devextreme-data-grid-forked-745xe?file=/App.vue
