Short description of error
New render window opens while another is open already.

Exact steps for others to reproduce the error

  1. 1 Open Blender
  2. 2 Create an object or use the default cube
  3. 3 Render (F12) (I usually render using the render window that appears floating, not a window inside the UI)
  4. 4 Save the file with the floating window open. (test_object_01.blend)
  5. 5 Close the file completely or open a new blank file (File > New > General
  6. 6 Open the test_object_01.blend
  7. 7 It should open with the render window open in the same place it was before.
  8. 8 Hit render (F12) and another render window opens.
  9. 9 Close the new render window
  10. 10 Render and it opens again

Confirming the bug but don't have to bisect this right now :(
