What is the current behavior? Drag and drop of text breaks the "select all" functionality

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

  1. Go to https://facebook.github.io/draft-js/
  2. Enter "Hello world test" in the input field
  3. Press Ctrl+A (Cmd+A on Mac OS) then backspace. Notice it deletes all the text (expected behaviour)
  4. Enter "Hello world test" in the input field again
  5. Double-click the word "test" to select it
  6. Drag and drop the word "test" after "Hello". The resulting text in the input field should be "Hellotest world", and your cursor should be after the word "Hellotest".
  7. Press Ctrl+A then backspace. Notice that the text is deselected, and it only deletes one character

What is the expected behavior? Ctrl+A backspace should behave the same in both scenarios

Which versions of Draft.js, and which browser / OS are affected by this issue? Did this work in previous versions of Draft.js? Latest version on Draft.js website (I'm also seeing this internally at Facebook) Chrome 55.0.2883.87 on Windows 10

Research direction
Investigate the Draft.js selection state management, particularly how drag and drop operations affect the internal selection. Look at the `EditorState` and `SelectionState` classes, and search for related issues or commits that might have addressed similar problems. The bug is reproducible with steps provided, so start by creating a minimal reproduction and tracing the selection after the drag and drop sequence.
