1.6 - Render in VFB, close, render in docked IR, can't open VFB again

Steps:

  1. render something in main VFB
  2. close it
  3. start a docked IR window and render away for a bit, then close it
  4. hit Show VFB - doesn’t open

What’s worse, it completely kills the VFB that you had before, so when I hit Render again, it opens up but my previous render is gone (with Clear VFB disabled).
