Importing a presentation from current project and choosing to override duplicate assets deletes the assets

Create a new presentation and add a text element to the presentation. Save the presentation and then import the currently open presentation into the project. As expected, you'll get a dialog box to choose overwrite or skip for the font asset. If you choose to overwrite, the font asset is just deleted. This happens because overwrite first deletes the old asset and then copies the new asset in its place, but in this case the old asset was also the source asset, so there is nothing left to copy. It should be checked if the source and destination asset is the same file and just ignore the import for those assets.
