Validations

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Make sure this is a Vite issue and not a framework-specific issue. For example, if it's a Vue SFC related bug, it should likely be reported to vuejs/core instead.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.

This is because we disable minification for lib mode.

vite/packages/vite/src/node/plugins/terser.ts

Lines 90 to 91 in ac32968

	// Do not minify ES lib output since that would remove pure annotations
	// and break tree-shaking.

Probably we can enable it and set comments: 'all' automatically.
