I'm on 11ty 0.11.0, and the version of liquidjs has a bug (https://github.com/harttle/liquidjs/issues/227) which has been fixed in v9.12.0. 11ty is still using v6.4.3. Please update it.
I tested liquid with and without eleventy. The bug is only present when using 11ty.
FWIW, as a workaround you can add the more recent liquidjs version as a dep and set your own liquidjs instance as detailed here. https://www.11ty.dev/docs/languages/liquid/#optional-set-your-own-library-instance
Same issue as #862 ?
@samuelpath I might be biased, but I think my issue describes the root problem more clearly. Should @barcia close their issue?

Does this break Eleventy in that it doesn't include templateContent or content with the collection items or page data any more?
I'll create a repo to check and report back, as I believe this is in fact happening.
Edit: Hmm, it doesn't.
Fixed in a37a5c675d97268dab50e83e4692e152be9fbf0d. Will be released in v1.0.0.
