-- rendered correctly - switch to "line chart"

• no reaction - browser needs to be killed
• Google Chrome Helper at 100% cpu

With Safari same output - but renders "Line chart" and then dies.

• Safari Web Content (Not Responding) - 100% CPU

Tried to analyze, but did not manage to find any issue.
Same reaction when debugging - the issue is somewhere in the async part.

As it worked in Dart 1.16, looked into changes, but did not see any potential causes.
