Description

• starting and finishing spans happen simultaenously, we’re not awaiting the span before to finish -> this is already a major issue in consistency
• Sentry.reportFullyDisplayed might finish the wrong TTFD span
  • Screen A starts TTFD and wants to finish it in the background after 5 seconds
  • Within those 5 seconds a user navigates to Screen B, Screen B starts TTFD span and replaces the TTFD span from A because they are global
  • Since the background work is still running the TTFD from Screen A is finished and reported as TTFD for Screen B which is false reporting
