"Overwrite existing file?" not always asked when adding same file again

In QDS 3.9 I would always need to confirm overwriting existing file in case I tried to import asset that already existed. See attached picture.

Testing with latest 4.0.0 snapshot, this seems to work a bit differently. I only get this confirmation question if I actually change the asset. Not sure what is the correct behavior here: always ask to confirm or only if the file actually changed (do we check this now somehow)?

Steps to reproduce:

• Create a project
• import some image asset to project in Images folder
• import the same image to same location again
• -> Not asked if existing file should be overwritten or not
• rename some other image to have same name as the one you imported, and import it
• -> now I get "Overwrite existing file?" dialog
