Support for <abbr> (and <dfn>) tag in richtext fields (CKEditor)

[iparr]

The <abbr> tag is helpful in making content concise but approachable.

Many responsible for CKEditor do not seem particularly convinced by its usefulness. I am determined to help you make Craft CMS a first-in-class editorial experience for technical and scientific publishing!

Can Craft CMS somehow support this? Ideally it would work thus:

1. Select the text that is to be marked as an abbreviation
2. A dialogue box opens, much like the one for a link - with a field showing the selected text and one showing the title attribute
3. The title attribute would be optional
4. Hitting 'Insert' provides the following HTML output: <abbr title="title attribute">text initially selected</abbr>

Note: I can currently add this manually using the 'View source' feature, but obviously this isn't practical for most users. To get this working I needed to add the following lines in my CKEditor config (I think so at least…):

htmlSupport:
    allow:
      -
        attributes:
          - title
        name: abbr

In a simple vein, <dfn> would be nice too.

In the first case, to be used much like <abbr>, with a title element - but ideally support for more advanced situations where abbr and dfn are combined could be desirable.
