Input fields: Floating label not translated to top when Outlined and FullWidth

[dbereghici]

Describe the bug
After setting the Outlined and FullWidth properties to true, the label is not translated to the top of the input.

To Reproduce
Steps to reproduce the behavior:

1. Set the Outlined="true" FullWidth="true" properties to an input field (MatTextField, MatAutocompleteList etc)
2. Write something in the input
3. See that the label is not moving to top when typing
   

Expected behavior

Possible cause
Since the upgrade for @Material from 4.0.0 to 6.0.0 (3fcf00b), the css selector is not specific enough:

v4.0.0:

v6.0.0:
