Text Spacing feature does not apply spacing following paragraphs

[dabrams888]

Describe the bug

SC 1.4.12 including the following style property:

Spacing following paragraphs to at least 2 times the font size;

For web-based content, it's recommended that this be tested using the following CSS:

p {
    margin-bottom: 2em !important;
}

Currently, the ARC Toolkit feature for adjusting text spacing seems to apply the other 3 properties from this SC, but not spacing following paragraphs.

To Reproduce

1. In ARC Toolkit, go to 'Highlight'
2. Select the option to 'Check Text Spacing'
3. Inspect the page styles and/or visually check the style differences on the page.
4. The following CSS is injected, which does not include paragraph spacing.

body.arcTextSpacingHelper * {
  line-height: 1.5 !important;
  letter-spacing: 0.12em !important;
  word-spacing: 0.16em !important;
}

Expected behavior

The Text Spacing feature in ARC Toolkit applies all of the style properties that are specifically called out in SC 1.4.12 to the best of its ability.

Note that I say 'to the best of its ability' here because there is an assumption that authors are using HTML <p> elements to define paragraphs of text. This is not always the case and it is not uncommon for authors to use generic <div> elements or similar for blocks of text. However, applying these properties to generic elements like <div> would be unwise, and not a good representation of the intent of this criteria.
