Environment details

OS: Sonoma 14.7
Node.js version: 20.11.1
npm version: 10.8.2
release-please version: 4

Steps to reproduce

Have a Monorepo with subpackages
Have these settings in release-please-config.json:

json

{
"include-component-in-tag": true,
"include-v-in-tag": true,
"tag-separator": "@",
"plugins": ["node-workspace", "sentence-case"],
"release-type": "node",
"commit-search-depth": 1,
"group-pull-request-title-pattern": "chore: release ${component} ${version}",
"pull-request-title-pattern": "chore: release ${component} ${version}",
"packages": {
  ".": {
    "packageName": "@packageTeam/root",
    "extra-label": "core",
    "exclude-paths": [
      "packages/package-a",
      "packages/package-b",
      "packages/package-c",
      ...
    ],
    "pull-request-title-pattern": "chore: release ${component} ${version}"
  },
  "packages/package-a": {
    "path": "packages/package-a",
    "packageName": "@packageTeam/package-a",
    "extra-label": "react-components",
    "pull-request-title-pattern": "chore: release ${component} ${version}"
  },
  "packages/package-b": {
    "path": "packages/package-b",
    "packageName": "@packageTeam/package-b",
    "extra-label": "web-components",
    "pull-request-title-pattern": "chore: release ${component} ${version}"
  },
  ...
},
"$schema": "https://raw.githubusercontent.com/googleapis/release-please/main/schemas/config.json"
}

When a release (via release-please-action) is created, and there are changes in the root package as well, everything works fine. I'll get a PR with the requested PR format.

The problem starts when I only have changes in my subpackage, then my PR title will just plainly be "chore: release (#issueNr)"

When release-please reruns, it stumbles and can't find the correct PR to the release, the autorelease: pending tag will not be removed, no release will be created.

Solution, for now, is to manually adjust every Pull Request's title and squash commit message, which is pretty time consuming and error prone.

Can you guys help?
