Any suggestions on how to stop it reappearing after another repaint?

Dilute PVA?

Why would a glue stop a stain? You need something that isn't water based.

Any oil based paint will do, though something dark to be covered with
white emulsion isn't a good idea. You can get proprietary stain blockers
but they are expensive compared to the left over can of white gloss on
shelf...
