Reproduced in 5.0.0beta5 (0e4b844)

With the difference that after closing A.kra on Win1 in Step 8, A.kra appears closed in both windows and B.kra is visible.

I notice that at this point Win1's document list in the Window menu only shows B.kra. However, Win2's document list contains A.kra and B.kra.

After closing B.kra on Win2 after Step 8, A.kra is revealed on Win2 and opened again on Win1.
