What steps will reproduce the problem?
(1) https://chromium-swarm.appspot.com/tasklist?c=name&c=state&c=created_ts&c=duration&c=pending_time&c=pool&c=bot&c=user-tag&c=name-tag&et=1539866400000&f=os%3AUbuntu-14.04&f=pool%3AChrome&f=name-tag%3Atelemetry_perf_unittests&f=master-tag%3Aclient.v8.fyi&l=1000&n=true&s=duration%3Adesc&st=1539778800000
(2) Look that there are results and some tasks have completed successfully
(3) Click on "Completed (Success)" in the right "Selected Tasks" column

What is the expected result?
Some successful results should be visible.


What happens instead?
Nothing is shown, because "name-tag" and "master-tag" were replaced with "name" and "master" dimensions.

If this is a regression (i.e., worked before), please consider using the
bisect tool (https://www.chromium.org/developers/bisect-builds-py) to help
us identify the root cause and more rapidly triage the issue.
