@moog16 This is an issue in MDC Web that has been fixed in v2.1.0
material-components/material-components-web#4637
https://github.com/material-components/material-components-web/blob/master/CHANGELOG.md#210-2019-05-06

[moog16]

@rbare1 thanks for linking those together. Could you update text field to latest v2.3.1? There are no breaking changes.

refs #885

[rbare1]

@moog16 Updated!

[moog16]

Please resolve conflicts. Looks good!

[rbare1]

@moog16 Rebased onto rc0.14.0

[moog16]

Can you add to the test/screenshot/golden.json file:

"text-field/noLabel": "03812f8c2eeb6bbfeb5bae4cdc7794a7ca760628e119edaec974d8f87740453c"

[rbare1]

The golden for fullWidth needs updated as well, since it has no label and gets the same mdc-text-field-no-label class that had the padding change in MDC Web 2.1.0
