dandanseo123 opened a new pull request, #65039:
URL: https://github.com/apache/airflow/pull/65039
### Description:
Group markers (`::group::` / `::endgroup::`) consumed line number indices
but were removed during group processing, leaving gaps in the displayed line
numbers (e.g. 0, 2, 3 instead of 0, 1, 2). Also fixed line number alignment on
wrapped log lines.
- Pre-scan log data to assign sequential display line numbers that skip
group markers
- Pin wrapped line numbers to the top with `alignItems: flex-start`
