Tests not closing down on after failed Detox test run

[ggilchrist-ledger]

I have some (expected) failing tests that should be closing after the test failure and Detox cleanup, but the CI step just hangs until the timeout-minutes has been reached. Is there something I should be doing to get the step to quit once the test has completed?

Android step yaml:

      - name: Run Android tests
        timeout-minutes: 15
        if: steps.avd-cache.outputs.cache-hit != 'true'
        uses: reactivecircus/android-emulator-runner@v2
        with:
          api-level: 29
          # force-avd-creation: false
          avd-name: Nexus_6_API_30
          emulator-options: -verbose -no-boot-anim -noaudio
          ram-size: 2048
          # disable-animations: true
          script: |
            adb logcat -c
            adb logcat *:E &
            $ANDROID_HOME/platform-tools/adb devices
            yarn e2e:test -c android.staging --loglevel verbose --record-logs failing --record-timeline all --take-screenshots failing

Error (starting from the Detox cleanup, and showing the emulator shutdown and then hanging). The key bit is Error: the action has timed out:
