Since the image util method `image_base64()` is converting BMP images to PNG
automatically[1], there would be a mismatch between the attachment content type
and the attachment mimetype.
- Content type: retrieve with `base64_to_image(data).format` -> return PNG as
the image data was converted from BMP to PNG
- Mimetype: set on `write()` and `create()` with `_check_contents()` which
call `mimetypes.guess_type(file_name)`.
BMP image `my_file_image.bmp` would have a mimetype set to BMP
The computed field `image_src` would return `False` since the image.mimetype
would be BMP, making the dialog picker not showing the image but loading
`http://localhost:8069/false` instead.
