Steps to reproduce
Some of the mathjax v4 symbols included in Obsidian v1.14 don’t look like they should.
In Obsidian 1.14.2 och higher, type into a note these two lines:
$\iint\quad\oiint\quad\oiiint$
$\displaystyle\iint\quad\oiint\quad\oiiint$
Did you read and follow the Troubleshooting Guide ? [Yes]
Expected result
Both \oiint and \oiiint should look like \iint. The mathjax website has a live demo that can show what the above math code is supposed to look like exactly.
Actual result
The mathjax code will display something like the second screenshot (see additional information section). It looks like the rendering does not have the necessary glyphs for the new mathjax symbols, and is thus falling back to another font (the symbols in the first screenshot (1.13.7 installer) look like unicode even). Mathjax v4 uses mathjax-newcm as the default font, but Obsidians DOM shows it landing on trying to use “MJX-TEX-ZERO” (courtesy of “purple penguin” in insider-desktop-release).

NOTE: I included \iint in the pictures since it is available in previous Obsidian versions (using mathjax v3) and because it shows how these symbols are supposed to look.
