What does this MR do and why?

Restore collapsible sections in job log viewer

Changelog: fixed

Additional validation

I tested this against the following raw log, which contains sections like:

remote: Compressing objects:  98% (118747/121170)        <CR>
remote: Compressing objects:  99% (119959/121170)        <CR>
remote: Compressing objects: 100% (121170/121170)        <CR>
remote: Compressing objects: 100% (121170/121170), done.

To show progress, so it works well for the cases shown by !153704 (merged).
