//! Regression tests for review finding R2-F1 — bare compound array
//! items (anonymous Object/Array elements) must survive the § 5.3.2
//! reopen-merge pass in `src/thin/merge.rs`. Pre-fix, an anonymous
//! compound's Begin pushed no merge stack frame while its closer popped
//! one, corrupting the merged stream: `ktav::from_str` panicked with
//! "stream is balanced; root frame always open" or failed with
//! "expected Key or EndObject in map, got Some(EndArray)" on VALID
//! documents.
