[v4.1.0] Spacing Difference Around "=" and "-" After Upgrading from MathJax 2.7.4 to 4.1.0

Issue description
We recently upgraded MathJax from version 2.7.4 to 4.1.0 in our web application. After the upgrade, we observed a visual change in how the symbols "=" (equals) and "-" (minus) symbols are positioned relative to adjacent input text boxes..

There has been no change in the LaTeX input. The only change is the MathJax version

Observed behavior in MathJax 2.7.4
In version 2.7.4, the "=" and "-" symbols are rendered with appropriate spacing and appear visually aligned relative to the input text boxes.

Observed behavior in MathJax 4.1.0
In version 4.1.0, there is no visible spacing between the symbols and the adjacent input text boxes, causing them to appear directly attached when compared to version 2.7.4.

Reproduction

• No change in the LaTeX input
• Only the MathJax version was upgraded to 4.1.0
• The issue specifically affects the rendering/spacing of the "=" and "-" symbols near input elements..

Summary

• MathJax 2.7.4: Symbols render with expected spacing.
• MathJax 4.1.0: Symbols appear closer to adjacent input text boxes.
• This results in a visible spacing difference in the UI

Question

1. Is this spacing change expected behavior in MathJax 4.1.0?
2. Is there a recommended configuration or approach to achieve rendering similar to MathJax 2.7.4?

Any guidance on supported or recommended solutions would be appreciated.

Start by running the attached Mathjax-4.1.0-math-symbol-close-TextBox.html and compare its output with MathJax 2.7.4 using the same LaTeX and input elements. Investigate whether the spacing change is expected in MathJax 4.1.0 and identify a supported configuration or approach that provides the earlier rendering, then document the result.
