display-buffer-reuse-frames makes View-quit abnormal

[an0]

After `(setq display-buffer-reuse-frames t)', `C-h f'(or `C-h v' and the alike) to view help, `C-x o' to jump to the help window, `q' to quit view mode, then I find `View-quit' does not restore window and buffer to previous state as usual, instead Emacs pops one of other buffers.
