Size of rendered math

[EukerionGW2]

Hi all,

First of all thanks to the creator of markdown-here which is a great tool and very convenient for professional emails (I'm using it with Thunderbird).

One thing bothers me a bit tho: I find that the size of the rendered math is much too big compared to the text (screenshot below). Anything that I'm missing? Is there a way to choose the size and/or fix the issue somehow?

Thanks in advance!
Cheers
Eukerion

This is a **Markdown-here** test.
I'm typing some LaTeX math here: $\int_0^{+\infty}f(x)\mathrm dx$...
... But the size of the rendered math is a bit big.```
