Is it a known issue that should operator does not print stacktrace on a failure? I have a matcher like this:

fun beEnabled(buttonModel: ButtonModel) =
  Matcher<ButtonModel> { model ->
    MatcherResult(
      buttonModel.isEnabled,
      { "expected $model to be enabled" },
      { "expected $model to not be enabled" }
    )
  }

fun ButtonModel.shouldBeEnabled(): ButtonModel =
  apply {
    this should beEnabled(this)
  }

On failure shouldBeEnabled throws assertion error without full stacktrace which makes it hard to figure out where that assertion failed exactly:

java.lang.AssertionError: [REDACTED]
expected ButtonModel(text=Continue, isEnabled=false, isLoading=false, leadingIcon=null, treatment=Primary, size=Footer, testTag=null, onClick=StandardClick(onClick=() -> kotlin.Unit)) to be enabled

When I change shouldBeEnabled implementation to this, I get the full stacktrace on failure, am I implementing a custom matcher wrong?

fun ButtonModel.shouldBeEnabled(): ButtonModel =
  apply {
    this.isEnabled.shouldBeTrue()
  }

Perhaps shortened stack trace related to coroutines. I suggest Decoroutinator for restoring stack trace in coroutines.
