The "check text spacing" option does not appear to set the paragraph spacing

[sasgrw]

Summary

When inspecting the CSS that is injected by selecting the "Check text spacing (WCAG 2.1)" option, the CSS only contains three of the four requirements by 1.4.12.

• Line height (line spacing) to at least 1.5 times the font size;
• Spacing following paragraphs to at least 2 times the font size;
• Letter spacing (tracking) to at least 0.12 times the font size;
• Word spacing to at least 0.16 times the font size.

<style type="text/css" id="ia11yVarsTextSpacingCss">
 *{line-height: 1.5 !important; 
   letter-spacing: 0.12em !important; 
   word-spacing: 0.16em !important;}
 </style>

(Note, format of block above was adjusted to make it easier to read but it was copy/pasted from the Chrome devtools inspector)

Expected result

I expected to see a 4th CSS property such as p{ margin-bottom: 2em !important; } to match 1.4.12's second bullet point.

Actual result

Three of the four requirements are properly applied. The fourth requirement is missing.

Test Case

Bring up any website and ARC Toolkit and check the box for "Check text spacing" then inspect the element of the page. The last element in the block is a <style> that was injected by the ARC Toolkit. It only contains three of the four CSS properties needed to test 1.4.12.
