## Description This PR fixes a `RangeError: Invalid language tag` that occurs in the Heatmap report when using locales with underscores (e.g., `pt_BR`, `zh_TW`). The issue was caused by passing the raw locale string from `vue-i18n` (which uses underscores for some regions) directly to `Intl.DateTimeFormat`. The `Intl` API expects BCP 47 language tags which use hyphens (e.g., `pt-BR`). This change sanitizes the locale string by replacing underscores with hyphens before creating the `DateTimeFormat` instance. Fixes #12951 |
