Coverage data is different between scala 2 and scala 3

[rolandtritsch]

How to reproduce?

• run sbt +clean +coverage +test +coverageReport
• look at target/scala-2.13/scoverage-report/index.html and target/scala-3.2.2-RC2/scoverage-report/index.html
• they are different (e.g. branch coverage)

• You can also diff target/scala-2.13/scoverage-data/scoverage.coverage target/scala-3.2.2-RC2/scoverage-data/scoverage.coverage

Questions to ask?

Note: It is expected that the "format/content" of the scala 3 scoverage.coverage file is somewhat different.

• Why are they (so) different?
• Which one is (more) correct?

Seems this was fixed here - scala/scala3#18420

Waiting for 3.3.2 (or 3.4.0).

VERY good news. Just tested this with 3.3.2-RC1 and this is fixed now!!!
