Rollup merge of #86542 - GuillaumeGomez:line-numbers-aligned-with-content, r=jyn514

Line numbers aligned with content

We had the issue a few times in the past where the source code pages' content wasn't aligned with the line numbers but completely below. This test will prevent this change to go unnoticed.

The first commit comes from #86541 so it needs it to be merged first.

r? `@jsha`
