Long labels in outlined inputs behave in a weird manner

[Floriferous]

When using longer input labels with selects and inputs of the outlined variant, the label width detection does not work properly.

Here's a reproduction: https://codesandbox.io/s/material-demo-3gqm2

It's also not really clear to me why the input does not resize when the label is down. But I guess that's just a limitation. I wish I could simply give it a label, and it'd take the space it needs to display it properly.

@Floriferous Same problem and limitation than #12255.
