Hi,
I have a following desired behaviour:
Updates are grouped by parentDir + automerge non-major deps

Config

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": [
    ":dependencyDashboard",
    ":label(dependencies)",
    ":enableVulnerabilityAlertsWithLabel(CVE)",
    ":prConcurrentLimitNone",
    ":prHourlyLimitNone",
    ":semanticCommitsDisabled"
  ],
  "recreateWhen": "always",
  "assigneesFromCodeOwners": true,
  "cloneSubmodules": true,
  // Order matters
  "packageRules": [
    // group all updates under single branch by cluster-name
    {
      "matchDepPatterns": [
        "*"
      ],
      // remove package specific text from commit message
      "commitMessagePrefix": "renovate:",
      "commitMessageTopic": "{{#if parentDir}}{{{parentDir}}}{{else}}cloud-aws{{/if}}",
      "commitMessageExtra": "",
      "commitMessageSuffix": "",
      // does actual grouping by forcing renovate/<topic> name
      "branchTopic": "{{#if parentDir}}{{{parentDir}}}{{else}}cloud-aws{{/if}}",
      "branchPrefix": "renovate/",
      "automerge": false,
      // prevents pipeline spam
      "rebaseWhen": "conflicted"
    },
    // enable automerge of non-major deps for whitelisted paths
    {
      matchFileNames: [
        "stages/eu-dev/**",
        "stages/mocca-dev/**",
        "stages/dmp-dev/**",
        "stage/sre-test/**"
      ],
      "matchUpdateTypes": [
        "minor",
        "patch"
      ],
      // disable the rule for 0.x.x as it allows non-major to have breaking changes,
      "matchCurrentVersion": "!/^0/",
      // branch name prefix
      "branchPrefix": "renovate-automerge/",
      // commit-name/MR-title
      "commitMessagePrefix": "renovate-automerge:",
      // enable automerge, rebase required
      "rebaseWhen": "auto",
      "automerge": true
    },

It usually works well, but also in some cases renovate change automerge and normal MR's places.

And as consequence - sometimes major releases have automerge enabled and MR content doesn't match the description.
I've attached the whole logs, but I think relevant part is around DEBUG: PR title changed entries.

Thanks in advance
