Release messages are being posted in related MRs

[privetkuku]

Hello!
When I run pnpm semantic-release on main, I get messages like "🎉 This MR is included in version" in closed/merged MRs. Same happens if I run canary releases, MRs without stable version also get a mention from semantic-release.
I would expect if I run release on main other MRs stay intact. If I run canary release on MR "my new feature", my merged but unreleased MR "my old feature" would not have "🎉 This MR is included in version" message. Is there a way to achieve this?
My release config:

import { Options } from 'semantic-release';

const config: Options = {
    branches: [
        'main',
        {
            name: process.env.CI_COMMIT_REF_NAME!,
            prerelease: 'canary-${Math.random().toString(36).substring(2, 15)}',
        },
    ],
    tagFormat: '${version}',
    plugins: [
        '@semantic-release/commit-analyzer',
        [
            '@semantic-release/release-notes-generator',
            {
                preset: 'conventionalcommits',
                presetConfig: {
                    issuePrefixes: ['prefix-'],
                    issueUrlFormat: 'https://test.com/{{prefix}}{{id}}',
                },
            },
        ],
        '@semantic-release/changelog',
        '@semantic-release/npm',
        [
            '@semantic-release/git',
            {
                assets: ['CHANGELOG.md', 'package.json', 'README.md'],
                message: 'chore(release): ${nextRelease.version}\n\n${nextRelease.notes}',
            },
        ],
        '@semantic-release/gitlab',
    ],
};

export default config;
