Mathjax corner case (Bbb + nested subscripts of symbols)

[jiryang]

Hi,

Somehow, Bbb (or mathbb) with nested subscripts of symbols seem to show strange behavior:

1. $E_{\pi_\pi}$, $E_{a_\pi}$, $E_{\pi_a}$ ---> all work fine
2. $\Bbb{E}{\pi\pi}$ ---> does not work
3. $\Bbb{E}{a\pi}$ ---> does not work
4. $\Bbb{E}_{\pi_a}$ ---> works fine

All of the above used to work fine.

Can you please provide a sample input and the output you get as well as the output you would expect?

Hi, the script does not seem to show correctly.

There should be 'underscore' character between two characters inside the parentheses of the two 'not working' cases.

Outputs are:

1. Eππ, Eaπ, Eπa (normal character + subscript + subscript of subscript style)
2. $\Bbb{E}{\pi\pi}$
3. $\Bbb{E}{a\pi}$
4. Eπa (blackboard bold + subscript + subscript of subscript style)

Thanks in advance!

Please provide the three parts - input, current output, expected output - as standard code blocks, like this:

Input:

Some $test$ here

Output:

<p>Some $test$ here</p>
