`\sqrt` with index of radical exceeds two digits display incorrect on v3.2.2

[azurechen]

Issue Summary

When using the sqrt syntax but the index of radical exceeds two digits, the offset of expression is incorrect.

For example

aa\sqrt[33333]{a^{15}} + \sqrt[33333]{a^{15}}aa

Steps to Reproduce:

1. Go to the demo page provided by MathJax-demos-web
2. input aa\sqrt[33333]{a^{15}} + \sqrt[33333]{a^{15}}aa and click Render TeX

The correct result should be displayed like the following image (the output is HTML, which means the issue is only on SVG)

After investigation, this is a bug caused by the following line. Seems like adding an extra dx value accidentally.

Remove this line, and the expression is displayed correctly.

I also create a PR to fix the issue https://github.com/mathjax/MathJax-src/pull/1098

Technical details:

• MathJax Version: 3.2.2
• Client OS: Mac OS X 114.4.1
• Browser: Chrome 125.0.6422.113
