Numbered, centered, long equations are incorrectly indented

Issue Summary

Numbered, centered, long equations are indented even though they shouldn't be. This means that long equations are flowing into the margin much sooner than they should be. Here is a screenshot:

Steps to Reproduce:

Please open the attached HTML file (see at the bottom).

The issue does not occur when equations are {unnumbered and centered} or {numbered and left-aligned} (via displayAlign: 'left'). The issue occurs both with SVG and CHTML.

Technical details:

MathJax Version: 3.2.2 (according to MathJax.version in browser console)
Tested with the following browsers:
- Firefox 105.0.3 (64-bit)
- Chromium 106.0.5249.119 (Official Build) Arch Linux (64-bit)
- Microsoft Edge Version 106.0.1370.47 (Official build) (64-bit)

I am using the following MathJax configuration:

MathJax = {
  tex: {
    tags: 'all'
  }
}

and loading MathJax via

<script 
  type="text/javascript"
  id="MathJax-script"
  async
  src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-svg.js">
</script>

Feature request

In addition to fixing this bug, it would be great if MathJax were able to put the equation number below the equation for long equations, like LaTeX does:

I can open a feature request for this separately should this be desired.
