Renaming an image without specifying its extension inside an "image" folder makes it disappear

[Arkounay]

Here's my conf:

artgris_file_manager:
  web_dir: public
  conf:
    default:
      dir: "../public/uploads/"
      type: image

If I upload an image there, and rename it without manually respecifying its extension:

it will disappear from the list because it's filtered out, since the list only accepts images.

the file will still be there and renamed properly however, just without any extension

Is there any way to improve this ?

Thanks
