upgradeCallbackinvocation onVersionErrorbefore wiping database contentThis change ensures that
upgradeCallbackis invoked when an IndexedDBVersionErroroccurs before any database wipe takes place. Today, whenwipeIfExists === false, theupgradeCallbackis never fired because the provider returns early while attempting to re-open the database (see early-return logic here: https://github.com/microsoft/ObjectStoreProvider/blob/78e1885d1e30e006a7d2252ce36f09e1cb772dd8/src/IndexedDbProvider.ts#L569C11-L577C12).Per MDN,
VersionErroris raised specifically during schema version downgrades—i.e., when opening a database with versionX - 1while it is currently initialized at versionX: https://developer.mozilla.org/en-US/docs/Web/API/IDBRequest/error#versionerror.By hoisting the
upgradeCallbackcall to occur immediately onVersionError, we guarantee that clients receive a reliable upgrade path even in downgrade scenarios. This allows clients to safely perform dependent cleanup operations (e.g., removing or migrating other dependent stores) before any potential database wipe occurs.
