Description: Commit f3e728aead1efc65d8b51b67bf9c14b1616d468c broke round-tripping of some files with charts. (MS Office will still load the resulting file, but it requests to "repair" it.) Steps to Reproduce: 1. In LibreOffice, open one of the attached .xlsx files (which were created in MS Office). 2. Save to .xlsx format. 3. Open the re-saved file in MS Office. Actual Results: MSO displays a pop-up asking to repair the file. Expected Results: MSO opens the file without needing to "repair" it. Reproducible: Always User Profile Reset: No Additional Info: Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: c850dd1c3636f1ad8dd5ac3d3b238c9b49acf23d CPU threads: 64; OS: Linux 6.14; UI render: default; VCL: gtk3 Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded
