Here is what happens step by step.
- We paste an image
- We know that there is an attachment in the pasted thing
- We show a placeholder text, like
- We start uploading the file
- We programmatically change the value of the textarea after upload finished
At this point Vue doesn't catch the programmatically changed textarea value. So in the
dropzone.js's paste handler I triggered
change event of the textarea manually.
