STEPS TO REPRODUCE
1. Open https://download.qt.io/development_releases/prebuilt/libclang/libclang-release_19.1.0-based-windows-vs2019_64.7z with `K7Zip::open()`
2. Call `(K7Zip*)archive->directory()->copyTo("/tmp");`
3. Wait for it to run into a Q_ASSERT in `KArchiveFile::copyTo`

OBSERVED RESULT

Assert(n == currentChunkSize)

EXPECTED RESULT

No errors / asserts etc.
