Inputs do not have margin with Horizon theme

[allen138]

Bug Description

Hi team, When using the Horizon theme, there should be a margin: 0.25rem 0 on the inputs. This applies for any inputs. When the webcomponent is placed next to either SAPUI5 sap.m.Input or a native input using fundamental styles which do correctly have this margin, this creates a misalignment. Please see:

Expected Behavior

When horizon theme is implemented, inputs should have a margin: 0.25rem 0.

Steps to Reproduce

1. Go to https://sap.github.io/ui5-webcomponents/playground/components/Input/?sap-ui-theme=sap_horizon&isrtl=false
2. Inspect the inputs and verify there is no margin.
3. Go to https://openui5.hana.ondemand.com/entity/sap.m.Input/sample/sap.m.sample.InputTypes?sap-ui-theme=sap_horizon&isrtl=false
4. Inspect the inputs and see there is a margin: 0.25rem 0
5. Go to https://sap.github.io/fundamental-styles/?path=/docs/components-forms-input--primary&globals=theme:sap_horizon
6. Inspect the inputs and see there is a margin: 0.25rem 0
