Poor kerning with subscripts, capital V, and an overmark

Created by: jason-s

\tilde{V}_d looks bad; too much spacing before the d, and it's not consistent with TeX. Other letters like \tilde{R}_d look ok.

I'm on Windows 10 but this is observable with Chrome, Firefox, and Opera.

Live example:

Source code:

<html>
<head>
<script>
MathJax = {
  tex: {
    inlineMath: [['$', '$'], ['\\(', '\\)']]
  },
  svg: {
    fontCache: 'global'
  }
};
</script>
<script type="text/javascript" id="MathJax-script" async
  src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-svg.js">
</script>
</head>
<body>
  <p>
Here is the issue: $V_d \quad \tilde{V}_d \quad \hat{V}_d \quad \hat{R}_d$ 
  </p>
  
<p>
Putting the subscript inside the overmark looks better for kerning, but is not a good idea: $\tilde{V_{sandwich}} \quad \tilde{V}_{sandwich}$
