Kotlinx Serialization annotation line included in the coverage report

[saurabh-somani-philips]

Describe the bug
Recently, I updated the Kover version in my KMM project from 0.8.1 to 0.8.3, and I noticed my data classes annotated with @Serializable were not fully covered. The annotation line looks yellow in the HTML report, stating it is partially covered.

I've tried excluding "*.*serializer*" from coverage report (as mentioned in some previous issue reported 1 or 2 years ago), but it didn't help.

Errors
N/A

Expected behavior
Data class should be fully covered, ignoring the @Serializable annotation line. I don't want to exclude the whole data class to solve this issue, just the annotation part. Am I doing something wrong or Kover needs to consider updating itself after Kotlin 2.0 update (I'm using v2.0.20)?

Reproducer
N/A

Reports
This is my data class in the Kover report:

This is the coverage summary:

Hi,
do you have the option to exclude companions ("*\$Companion") for serializable classes from the report?
If so, does it fix your issue?

@shanshin
I tried excluding it from the coverage report. The Companion object's coverage disappears, but main data class's 'Branch' and 'Instruction' coverage still has some coverage left. The same is reflected in our SonarQube report, so the ultimate aim is to fix the Sonar report coverage.

Similiar issue with android's @parcelize

Confirming I have this issue too with @Serializable

@shanshin , we have this problem too! This is very disturbing.
We left with Jacoco to Kotlin, because it has the same problem, but Kover also had the same problem after Kotlin update to 2.0

When is it planned to be fixed?
