Porting the MathJax display from previous DSpace versions

[jonas-atmire]

Description of the feature request Previous versions of DSpace contained the possibility of enabling the rendering of scientific formulas and symbols on different item pages. This should also be ported to DSpace 7 for preservation of default functionality.

An example of how this is currently displayed in DSpace: The 2 formulas that are present in the abstract are:

• $\text{H}_2$/$\text{O}_2$
• $\text{H}_2 + \text{O}_2(1\Delta) = \text{H} + \text{HO}_2$

When actually displaying the values, it's rendered as an actual formula, and not simply as the text that is present in the DB

Describe the solution you'd like The current configuration possibility should be ported to the DSpace 7 codebase. Most, if not all, of this work would be present in the angular side of things. Rest should only be relevant for the enabling/disabling of the config.

Agreed, this should be ported. However, at this time, I'd put this as relatively low priority unless we determine this is frequently used (my sense is it's not used by many). So, at this time, putting it in Tier 4, but flagging as help wanted in case a volunteer wants to implement/donate it earlier.

This is part of a larger issue: in earlier releases, textarea fields could be formatted. In 7.3, line breaks entered in the item editor are removed, and entering even plain HTML markup causes it to be displayed as-is.

We have abstracts with multiple paragraphs and even tables. Line breaks are quite common. Markup is rare but we have some.

The 7.x documentation still has a page on "Simple HTML Fragment Markup" which is no longer true and probably does not represent well the eventual resolution of this issue.

Added a zero hour estimate as this will be include in fix for #1762
