Single + in superscript or subscript

[geoffreymcgill]

We ran into a very specific scenario using a + in superscript or subscript that appears to fail parsing correctly.

Sample 1

Superscript^+^ or Subscript~+~

The above renders as...

Sample 2

If a space is added before the ^+^, then it parses correctly:

Superscript ^+^ or Subscript ~+~

The above renders as...

Sample 3

Interestingly, using ^+^ also fails:

Superscript^+^ or Subscript~+~

The above renders as...

The parsing issue only happens when using a single + char. If revised to a - char, then the subscript and subscript parse and render correctly.

Can anyone else reproduce?

Hope this helps.
