Material labels use too much vertical space when containing certain characters

[lucas-koehler]

Describe the bug
If material react labels contain certain characters (e.g. . or - and possibly more), they grab too much vertical space. It seems like the additional space grabbed is the same as if the label were wrapped once due to insufficient horizontal space (see screenshots below).

To Reproduce
Steps to reproduce the behavior:

1. Have a UISchema with three (or more) horizontal layouts below each other (e.g. in a vertical layout)
2. Have a row which only contains labels without special characters
3. Have another row with at least one label containing special characters
4. The row with the special character is too high even if there is sufficient horizontal space.

Expected behavior
The labels with special characters don't use excessive space if there is enough horizontal space.

Used ui schema:

const UISCHEMA = {
  type: 'VerticalLayout',
  elements: [
    {
      type: 'HorizontalLayout',
      elements: [
        {
          type: 'Label',
          text: 'X',
        },
        {
          type: 'Label',
          text: 'Y',
        },
        {
          type: 'Label',
          text: 'ZZ',
        },
      ],
    },
    {
      type: 'HorizontalLayout',
      elements: [
        {
          type: 'Label',
          text: 'X',
        },
        {
          type: 'Label',
          text: 'Y',
        },
        {
          type: 'Label',
          text: 'ZZ',
        },
      ],
    },
    {
      type: 'HorizontalLayout',
      elements: [
        {
          type: 'Label',
          text: 'X',
        },
        {
          type: 'Label',
          text: 'Y',
        },
        {
          type: 'Label',
          text: 'Z-Z',
        },
      ],
    },
    {
      type: 'HorizontalLayout',
      elements: [
        {
          type: 'Label',
          text: 'X',
        },
        {
          type: 'Label',
          text: 'Y',
        },
        {
          type: 'Label',
          text: 'ZZ',
        },
      ],
    },

This seems to be a weird issue. For some reason the browser has an issue with the special character.
A possible fix with side effects would be adding white-space: nowrap to the label element via CSS.
Documentation on this can be found here: https://developer.mozilla.org/en-US/docs/Web/CSS/white-space

The side effect is, that for long texts the text does now not break into multiline anymore.
