Hello,
I'm using the latest version of Chrome on Ubuntu 24.04.
The Code
<math forcemathmode="native">\int_\Sigma</math>
will be renderted as
But thats wrong. It the parameter \limits is not used then the set \Sigma should be rendert like
<math forcemathmode="native">\int_\Sigma^{}</math>
So if the upper border is missing the integral looks not correct.
