When using only static icon imports from Blueprint there is no need to import blueprint-icons.css, however with the latest change the icons are broken if the CSS is not imported.

Environment

• Package version(s): core@5.8.0 | icons@5.6.0
• Operating System: Windows 10
• Browser name and version: Chrome 120

Code Sandbox

Steps to reproduce

1. Do not import blueprint-icons.css
2. Use a static icon, i.e. <Download size={16} />

Actual behavior

Icon is not rendered correctly due to missing transform-origin: center; styles.

Expected behavior

Expected the icons to render correctly without needing to import blueprint-icons.css

Possible solution

Move the new styles to blueprint.css
