What is the expected behavior?

Space between icons and text should be 16px for both leading or trailing icons.

What is the actual behavior?

https://material-components.github.io/material-components-web-catalog/#/component/text-field

• Space between leading icon and text is currently 8px, for filled and outlined text fields
• space between trailing icon and text is 12px for filled text fields and 8px for outlined

Any other information you believe would be useful?
