Javadoc: CSS margin is not applied consistently

A DESCRIPTION OF THE PROBLEM :
It appears the javadoc Standard Doclet does not apply CSS margin consistently, instead some elements have no margin or only left and bottom margin and then only some of the contained elements have margin on the right.
This causes cases where margin is missing behind the end of the text, or where text in one paragraph is wrapped at a different point than text of another paragraph.

Affected cases (list is likely incomplete):
- Class documentation:
  The regular text has no margin on the left, causing it to be at the same horizontal position as <hr> element at the top, but has margin on the right causing it to end slightly before the end of the <hr>.
  On the other hand, the content of block tags in the class documentation has no margin on the right causing it to be as wide as the <hr> element.
- Method documentation:
  Regular text has margin on the right, causing it to end slightly before the white background ends.
  On the other hand, block tags (their name and their content) have no margin on the right causing their text content to sometimes directly end exactly at the end of the white background.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
This can be seen best when inspecting the HTML elements using the web browser, but is also visible by for example having a look at methods with "API Note" (or similar block tags which contain long sentences) and then zooming in and out until the text directly reaches the end of the white background.
