/**
 * Forget + fbt inconsistency. Evaluator errors with the following
 *   Found differences in evaluator results
 *   Non-forget (expected):
 *   (kind: ok) 1 rewrite to Rust · 2 months traveling
 *   Forget:
 *   (kind: ok) 1 rewrites to Rust · 2 months traveling
 *
 * The root issue here is that fbt:plural/enum/pronoun read `.start` and `.end` from
 * babel nodes to slice into source strings for some complex dedupe logic
 * (see [_getStringVariationCombinations](https://github.com/facebook/fbt/blob/main/packages/babel-plugin-fbt/src/JSFbtBuilder.js#L297))
 *
 *
 * Since Forget does not add `.start` and `.end` for babel nodes it synthesizes,
 * [getRawSource](https://github.com/facebook/fbt/blob/main/packages/babel-plugin-fbt/src/FbtUtil.js#L666-L673)
 * simply returns the whole source code string. As a result, all fbt nodes dedupe together
 * and _getStringVariationCombinations ends up early exiting (before adding valid candidate values).
 *
 *
 *
 * For fbt:plural tags specifically, the `count` node require that a `.start/.end`
 * (see [code in FbtPluralNode](https://github.com/facebook/fbt/blob/main/packages/babel-plugin-fbt/src/fbt-nodes/FbtPluralNode.js#L87-L90))
