🤖 Dependency Update Adoption Status

Status: ⚠️ REQUIRES INVESTIGATION

Analysis

• Dependency: happy-dom 15.11.7 → 20.4.0
• Type: Major version update (npm devDependency)
• CI Status: Failing - Web Quality Gates

Breaking Changes in happy-dom 20.x

happy-dom is a DOM implementation for testing. Version 20.x includes:

• Improved DOM API compatibility
• New window/document features
• Potential test behavior changes

CI Failures

• Web Quality Gates: FAILURE
• Secret Scanning: FAILURE (unrelated)

Recommendation

As a test dependency, this upgrade may cause test failures due to:

1. More strict DOM compliance (tests relying on loose behavior)
2. Changed default configurations
3. New APIs that conflict with test mocking

Action:

1. Review failing test logs to identify specific issues
2. Update test configurations if needed
3. Consider incremental upgrade (15 → 16 → 17 → etc.) if changes are extensive

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
