We will soon be migrating page previews out of beta features over the course of the month at which point this will magically solve itself.
It may create more work for us now to fix it so we should be mindful of that.
I've tested rEPOPd9d2be5de4a9: Remove hard dependency on BetaFeatures locally by not loading the BetaFeatures extension and it WFM. @Prtksxna has also tested it too (thanks @Prtksxna!).
