We sometimes loose data, e.g. between edge-beta bots (3 platforms) only 1 platforms appears on the dashboard. For some runs others appear.
Our speculation is that there is a race here:
playwright/utils/flakiness-dashboard/processing/dashboard_raw.js
Line 21 in 80ff7c3
Lets see if thats the case and limit it to 1 which should be enough for our scale.
See here, that its by default 8 * the number of CPUs.
