the code handling that is in https://github.com/geosolutions-it/MapStore2/blob/2023.02.xx/web/client/epics/catalog.js#L377 - does your text/xml md link finish with the xml view ? here it works fine.

I don't think the MD link is the problem as it work fine on the MS home viewer.
It looks like it's handled differently on contexts viewers.
