When you drag and drop an image into the editor, it is only temporarily uploaded, and the image address has issues even after the save action. This was fixed in Filament v3, but it is no longer working.
It works fine when you upload an image using the "Insert Image" option in the toolbar; when you click the save button, it handles the upload process correctly.
