precompilation failure of 1.6.5 in 1.10 - require_one_based_indexing

Apparently this should not error, because StaticArrays is set to be compatible with Juila 1.6, but this is causing issues in CI Downgrade tests:

Reproduce the failure with Julia 1.10 and StaticArrays 1.6.5 using the package-manager commands in the report. Start at src/StaticArrays.jl:1, where loading fails on require_one_based_indexing, then run the downgrade CI tests. Done means StaticArrays 1.6.5 precompiles successfully on Julia 1.10 without breaking the stated Julia 1.6 compatibility.
