A quick bit of experimenting, I can make the on-canvas dialog disappear and not return.
I edited the sessionrc file, setting the position to something stupid and started GIMP:
No dialog visible. Close GIMP and set it to (position 0 67) and re-start GIMP - it puts the dialog back in the top right of the visible canvas.
Edit: And now I can't repeat it.

Code:
(session-info "toplevel"
(factory-entry "gimp-scale-tool-dialog")
(position 1000 67))
No dialog visible. Close GIMP and set it to (position 0 67) and re-start GIMP - it puts the dialog back in the top right of the visible canvas.
