Description

Issue Summary

I noticed while using version 4 and auto-voicing that under certain conditions, the modifier "bold" was voiced simultaneously with the letter that it modifies.

Steps to Reproduce:

I did this in Firefox on a Mac.

  1. Go to the demo page.
  2. Change the demo input to $$\nabla \times \vec{\mathbf{B}}$$
  3. Put focus on the math output, and engage auto-voicing. Navigate in to the node for the boldface B, like so:

What I hear sounds like "bold" and "B right arrow" are voiced simultaneously. (This does not happen when the navigation is higher in the tree and voicing reaches that letter.)

Technical details:
  • MathJax Version: 4.1.0
  • Mac OS Tahoe 26.2
  • Firefox 147.0.3

Research direction

Start at the MathJax demo page with auto-voicing and reproduce the expression $$\nabla \times \vec{\mathbf{B}}$$ in Firefox on macOS. Inspect the navigation and voicing behavior for the boldface B node; done means the "bold" modifier is not voiced simultaneously with the letter it modifies.
