I have noticed over the past few days, that the merged reports for my repository seem to be excluding some reports. The excluded reports have been uploaded (I can see the raw data), but the information they contain is not reflected in the merged report (lines that are covered in the excluded report are not covered in the merged report).
Steps to Reproduce
I am not sure if this occurs for anyone else, but you can see lines 9 & 10 are marked missing from the merged report for the yggdrasil/serialize/init.py file here, but there are hits for those lines in the raw report for build/job 2941.8 here.
Expected behavior: All of the reports are merged.
Actual behavior: Only some of the reports are included resulting in lines marked missing that are only covered in the excluded reports.
Flakiness? This has been constant for the past few days, unsure when it began exactly, but definitely started within the past two weeks.

The excluded reports are not for the same jobs (i.e. different jobs are excluded each time I trigger a new build).
