Job log omits line numbers at end of sections

Summary

When viewing any Job log line numbers are omitted from the end of every section. In the screenshot the lines 97, 113, 115, 117, 125 and 127 are missing.

At the time of reporting, all environments, other than locally running the GDK, exhibit this behavior.

Steps to reproduce

• View the console output when the job is complete.
