exponentialE in math-ml

[kubaPod]

Description

\exponentialE is not converted to math-ml well

Steps to Reproduce

e e ^ 2 produces \exponentialE^2 (stringified it shows "\\exponentialE^2") yet

mathlive.convertLatexToMathMl("\\exponentialE^2") // or mf.getValue('math-ml')

<msup><mn>2</mn></msup>

on the other hand

mathlive.convertLatexToMathMl("\exponentialE^2")

<msup>exponentialE<mn>2</mn></msup>

which is better but weird that \e is used, either way something is off.

Additionally it should be something more standard thatn exponentialE in mathml, e.g. Mathematica produces:

<msup>
  <mi>&#8519;</mi>
  <mn>2</mn>
 </msup>

And I just found ⅇ in https://www.w3.org/TR/REC-MathML/chap4_1.html

Expected Behavior

I am not a LaTeX expert so correct me if I am wrong but I'd expect:

mathlive.convertLatexToMathMl("\\exponentialE^2") 

<msup>
  <mi>&ExponentialE;</mi>
  <mn>2</mn>
 </msup>

Environment

MathLive version 0.87.1

Operating System Window 10

Browser Chrome

I will post a separate issue later but this seems to be related:

mathlive.convertLatexToMathMl("x^2")

<msup>x<mn>2</mn></msup>

Shouldn't it be <mi>x</mi>?
