Compiler warning when using TestPath implicits as shown in Doc

[bwbecker]

With scala 2.13.5 I'm getting compiler warnings when using the TestPath implicit. That's new after an update from scala 2.12.x.

[warn] /Users/bwbecker/oat/src/oatlibxp/oatlibxp/src/test/scala/oatLibXP/verify/ImplicitTest.scala:13:21: method copyArrayToImmutableIndexedSeq in class LowPriorityImplicits2 is deprecated (since 2.13.0): Implicit conversions from Array to immutable.IndexedSeq are implemented by copying; Use the more efficient non-copying ArraySeq.unsafeWrapArray or an explicit toIndexedSeq call

Here's the code:

package oatLibXP.verify

import utest._
import utest.framework.TestPath

object ImplicitTest1 extends TestSuite {

  def f(x: Int)(implicit testPath: TestPath): Unit = {
    testPath.value.mkString(" ") ==> "causes a compiler warning"
    x ==> 42
  }

  val tests = Tests {
    test("causes a compiler warning") {
      f(42)
    }
  }
}

object ImplicitTest2 extends TestSuite {

  def g(x: Int, testPath: TestPath): Unit = {
    testPath.value.mkString(" ") ==> "causes a compiler warning"
    x ==> 42
  }

  val tests = Tests {
    test("causes a compiler warning") {
      g(42, implicitly[TestPath])
    }
  }
}

Also, the TestPath section of the Docs uses the now deprecated "test description" - { ... } format.

Is there any update on this issue? Any way to work around the warning?
I am trying to get chiseltest to compile without warnings and it looks like everyone who uses our utest based trait will get this warning when using Scala 2.13: https://github.com/ucb-bar/chiseltest/blob/129d82c952d18d9753e622ae3d9b5d53c79b059a/src/main/scala/chiseltest/ChiselUtestTester.scala#L77

I'm still getting the error, too.
