--action blocks until button is pressed or notification expires

[whew-inc]

My use case:

1. Take a screenshot
2. Show a notification using this library saying it's uploading to hosting service, show a button to copy the raw image to clipboard in meantime
3. When done uploading, replace the original notification with one containing 2 buttons: one to copy the url of the image and one to copy raw image

Issue: notify-send with --action parameter won't return until action is triggered or notification expires. This means I can't start uploading the image until one of either happens.
