Firefox problem with image tool and data URL

[brettz9]

In Chrome, when I visit the latest at https://svg-edit.github.io/svgedit/releases/svg-edit-3.0.0-alpha.4/editor/svg-editor.html and add the data URL below (from #192) via the "Image Tool" icon on the left toolbar, I get an image ok.

In Firefox, nothing appears to happen except for an alert.

It's not a valid base64. Did you copy the string from browser? I can see AQQQAABB...IIIIDAVAKE in the string.
