Hang while running test suite for scalatestplus-scalacheck (possible regression)

[griggt]

Running the test suite for scalatestplus-scalacheck appears to hang indefinitely (while shrinking?) when built against the latest commit on the scalacheck main branch (7749c38).

The same test suite passes within about 5 seconds if built against the previous merge commit (dc93d79), so it seems related to #838.

This issue was noticed while updating projects in the Scala 3 community build (scala/scala3#15728 (comment)) however it is also reproducible on Scala 2.13.

Reproduction Steps

1. publishLocal scalacheck @ 7749c38
2. clone scalatest/scalatestplus-scalacheck@32e7dc6
3. update build.sbt of scalatestplus-scalacheck to use the locally published scalacheck:

-    "org.scalacheck" %%% "scalacheck" % "1.16.0",
+    "org.scalacheck" %%% "scalacheck" % "1.17-7749c38-SNAPSHOT",

4. run sbt scalatestPlusScalaCheckJVM/test

I've been meaning to do a release, but we'll hold for this fix. Thanks for catching it!

I haven't tested with scalatestplus-scalacheck, but it should be fixed in 1.17-8689ae7-SNAPSHOT.
