[TheStreamCode]

Re-opening does not change the finding: Babel 8 is a breaking major that breaks the Jest transform across all 36 suites (@babel/core 8 changed the transform/preset contract). Closing again; this needs a dedicated Jest/Babel migration, not an automatic update. If it keeps reopening, add a @babel/core major ignore in .github/dependabot.yml.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
