Raindrop fails to bookmark local pdf files when opened in the browser.
Often when you click on a pdf on a website, it gets automatically downloaded locally, e.g. to "D:\Downloads\<some-file>.pdf" or "~/Downloads/<some-file>.pdf" and then opened in a new browser tab.
Currently if I click Raindrop's bookmark button for that local pdf, I get this error:
Raindrop validation failed: link: url is invalid. In order to upload the file, I have to go to the file's location in the explorer and drag'n'drop it or click the upload button in Raindrop and then navigate to the file's location.
