Source Map Loading Errors

Browser is Safari 27.0.1 on MacOS latest release.
Running NodeRed 5.0.8 on RPI (Debian Trixie)

What I'm finding is that Node Red screens are continually fully refreshed when selecting a tab. Every time it refreshes it returns to the first tab, so I can't actually get at tabs to change nodes etc.

The Safari debug shows lots of 404 errors - unable to load map files (which don't exist).
e.g. ```Cannot GET /vendor/purify.min.js.map

This used to work fine but some recent upgrade has clearly broken this.
Any ideas as to how to fix this?

Thanks
