[Bug] yarn workspaces foreach only running in a single directory, on node 15

• I'd be willing to implement a fix

Describe the bug

yarn workspaces foreach run is only running in a single workspace, rather than in every workspace, when run with node 15.8.0. On Node 12 and Node 14, this works correctly.

To Reproduce

Install node 15.8.0 (e.g. with docker, by running docker run -i mhart/alpine-node:15.8.0), and run the following commands.

mkdir mwe; cd mwe
echo '{ "private": true, "workspaces": [ "w1", "w2" ] }' > package.json
yarn set version berry
yarn plugin import workspace-tools
mkdir w1 w2
echo '{ "name": "@mwe/w1", "scripts": { "test": "echo passed w1" } }' > w1/package.json
echo '{ "name": "@mwe/w2", "scripts": { "test": "echo passed w2" } }' > w2/package.json
yarn
yarn workspaces foreach run test

This only logs passed w1, compared to passed w1 passed w2 on Node 14 and older versions.

I was not able to reproduce this in Sherlock, because (as far as I can see) it does not let you choose the version of Node.

Screenshot

Note that, for whatever reason, this Docker image does not have any characters at the start of the prompt. In these screenshots, all but the last line is pasted together, and then the final line is pasted after everything has run through.

Environment if relevant (please complete the following information):

• OS: macOS 10.15.7, and mhart/alpine-node
• Node version 15.8.0
• Yarn version 2.4.0
