Description of the bug:

Prior to upgrading to bazel 6.0.0, on a setup with remote execution, with bazel test --remote_download_toplevel --nozip_undeclared_test_outputs I'd see test.outputs populated with files.
On bazel 6.0.0, test.outputs is always empty on passing tests.

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

With remote execution, run bazel test --remote_download_toplevel --nozip_undeclared_test_outputs. Observe that test.outputs is empty on passing tests.

Which operating system are you running Bazel on?

Linux

What is the output of bazel info release?

release 6.0.0

If bazel info release returns development version or (@non-git), tell us how you built Bazel.

No response

What's the output of git remote get-url origin; git rev-parse master; git rev-parse HEAD ?

No response

Have you found anything relevant by searching the web?

No response

Any other information, logs, or outputs that you want to share?

If I remove --nozip_undeclared_test_outputs, I see test.outputs/outputs.zip on passing tests too
If I remove --remote_download_toplevel, I see the desired files in test.outputs/* on passing tests too

Adding --experimental_remote_download_regex=".*" didn't help.
