As a Confluence user I would like to copy and paste attachments from the clipboard to a Page

Summary

Pasting images from the clipboard into a Confluence Page does not work (only some times).

Steps to Reproduce

1. Copy a file from the web, from a desktop file or from a screenshot
2. On the Confluence editor, right-click with the mouse and select "Paste"

Expected Results

The image will be uploaded and inserted into the Page's body.

Actual Results

The image gets uploaded, but is not inserted into the Page's body.

PS: we can confirm the image is uploaded from the Attachments section on the Page.

Workaround

1. Use the keyboard shortcut (Ctrl+v for Windows or Cmd+v for MacOS) to Paste the image.
2. Save the image to a local desktop file and use the "Drag and Drop" feature.
3. Use the "Insert files or images" button to open the file navigator on the computer. Then, select a file and proceed with the upload of the attachment.

Notes

Firefox 51.0.1 - Drag and drop works, copy and paste doesn't work and brings a sample png
Chrome 56.0.2924.87 - Drag and drop works, copy and paste doesn't work and brings file name only eg: sample.jpg
Safari 9.1.2 - Drag and drop works, copy and paste brings the local path of the file to the page e.g: file://Userdirectory/folder/file.jpg

Nothing relevant on the logs.

Copying and paste or drag and dropping the file from the Sketch editor doesn't work in Chrome.
