Any additional comments?

As of the current extensive testing with beta.47, this bug seems to only happen strictly with r.default access dynamic import, it does not happen to top-level import { default as x } and other top-level/dynamic import access pattern like access r directly, or r.hello, etc.
This bug first appeared in beta.44 with the json tree-shake feat.

FYI: Why not just use r without .default, it works normally:
For some runtime, .default is required.
