Source PDF is indeed incorrect (according to spec). MacOS Preview and Chrome opens the file. Document -> [testinis dokumentas.pdf](https://github.com/user-attachments/files/19385905/testinis.dokumentas.pdf) Relaxed validation -> [relaxed.txt](https://github.com/user-attachments/files/19385914/relaxed.txt) Not sure how to handle such cases.
