Rename Editor JSX Test Files

[ciampo]

What?

See #80855.

TL;DR: This mechanical filename-normalization slice renames the 25 remaining JSX-bearing Editor Jest tests from .js to .jsx, renames the three Jest snapshot files whose paths depend on those test filenames, and updates the parser and executable-baseline manifests.

Why?

The native Vite end state must not treat every .js file as JSX. Normalizing JSX-bearing test filenames before changing their runner keeps extension changes independently reviewable and preserves the exactly-one-runner identity of every baseline test.

How?

• Renames 25 Editor test files without changing their test behavior.
• Renames three snapshot files to the paths Jest derives from the new .jsx test filenames. Each old/new snapshot pair was compared and is byte-identical.
• Records all 25 original-to-current test identities in the migration manifest.
• Reduces the parser-backed JSX-in-.js baseline from 1,177 to 1,152 files.
• Reorders one pre-existing WordPress dependency import exposed by strict linting of the new .jsx path; no runtime or assertion behavior changes.

Testing Instructions

1. npm run test:unit -- packages/editor --runInBand
   • 58 suites passed, 733 tests passed, 8 snapshots passed.
2. npm run --workspace @wordpress/unit-tests test:unit:routing
   • 996 baseline tests have exactly one runner and environment; 100 original test identities now map to renamed paths.
3. npm run lint:jsx-extensions
   • Validates the 1,152-file remaining JSX-in-.js baseline.
4. Commit-time formatting and strict JavaScript lint pass.
