IntelliJ Flutter test runner hangs when running "flutter test --platform chrome"

The IntelliJ Flutter test runner succeeds when not specifying a platform (i.e. VM). Change the Flutter test runner configuration to specify additional args of `--platform chrome` and the test runner hangs. The terminal command `flutter test --platform chrome` succeeds.

We expect the IntelliJ test runner to succeed and display the results. This has worked in the past (last time I did this was at least a few years ago).

To test platform specific functionality (e.g. web storage) we need to run some tests on a given platform.

## Steps to Reproduce

- In a Flutter web project with tests (i.e. create the default Flutter project with web target), create a run configuration for "Flutter Test" (the default project has `test/widget_test.dart`).
- Run the test in the IntelliJ test runner and confirm that the test results/errors are displayed.
- Change the Flutter test run configuration `Additional args:` to include `--platform chrome` and save.
- Run the test again, the IntelliJ test runner starts with `Instantiating tests...`, a chrome browser window opens with a tab `Flutter Test Browser Host`, and then hang...

You can verify that the tests can run by opening a terminal on the project and running the command `flutter test --platform chrome`.
