Math is read with unnaturally long pauses

[Neurrone]

Steps to reproduce:

1. Go to this page
2. Read the first equation in section 14.4 Conditional probabilities

Actual behavior:

The terms of the equation are read with unnaturally long pauses, which makes reading longer expressions incredibly slow.

clickable    Pr 
<pause>
times  
<pause>
open paren   
<pause>
Card 2 is a king  
<pause>
divides 
<pause>
Card 1 is a king 
<pause>
close paren   
<pause>
equals 3 
<shorter pause>
divided by   51 

Expected behavior:

In the past, these pauses were not present while reading math. I would like that behaviour to be restored, or at least for these incredibly long pauses to be shortened.

Any updates? This is a serious regression for MathML users.

is this now better with NVDA 2024.4.1? @Neurrone which add-pon are you using to read math with?

I'm using MathCat now and it doesn't happen for me anymore, closing.
