This seems to be a regression - first reported in OTRS: https://ticket.wikimedia.org/otrs/index.pl?Action=AgentTicketZoom;TicketID=9987589

Steps to reproduce

1. Open an article while online
2. Tap on a link preview in the article and select the overflow to "Open in a new tab"
3. Long press on another link to "Open in a new tab"
4. Wait 10secs then go into airplane mode
5. Navigate to read the two articles opened in the new tabs

Expected

Both articles should have been loaded at the point "Open in a new tab" was selected and user should be able to read those cached articles

Actual

Articles were not loaded.
