## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

We added a `min-height: 56px` to the input, textarea, and select
components for MD mode. However, these were added for the outline/solid
style inputs to align with the Material Design spec:
https://material-components.github.io/material-components-web-catalog/#/component/text-field

They should not apply to regular inputs in an item. The end result is
inconsistently sized items when used with non-control items.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Non-filled and non-stacked/floating label controls are now have a
minimum height of 44px.

There should be **no changes** to the following types of controls:

1. iOS controls (all variants)
2. MD filled controls
3. MD stacked controls

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->


## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->

Dev build: `7.5.2-dev.11697818830.1a33c881`
