Tested on Windows 11 64-bit with LibreOffice 25.8.3.2 stable (X86_64) and 26.2.0.0.alpha1+ beta (X86_64).

Reproduced the author’s table in Writer and repeated all steps: selecting a row up to a vertically merged cell.

Result: instead of a single row, multiple rows get selected, making it difficult to adjust borders or select a specific row precisely.

Conclusion: the issue is reproducible in both versions. The root cause is the handling of vertically merged cells: the program selects the entire merged range rather than the individual row. The way the tables were merged by the author may also influence behavior, but the main problem is the selection logic with vertical merges.
