Can not copy image if no leading content and not copy as base64 data from clipboard

[yinhm]

Description When in a new line with no leading content, then copy image does not work, and cause the editor entering state which can not edit(may work after like 10 seconds). When typing something, then can paste image as <image src="..." />

And when using some random image from a web page, right click then copy to slate editor, image paste as <img src="http://example.com/someimage.png" /> instead of base64 encoded content. Open a desktop from computer then copy to clipboard and paste to slate editor do work as expected.
