[1.20] Profile readme seems to be trimmed before rendering

[b1ek]

Description

I wanted to try out the profile readme thing, but it isn't rendered as its supposed to be. I can't upload an image, but you can see it on my gitea instance and how its supposed to be

I looked over the code, and the thing seems to be locateed here. My guess is that the markdown.RenderString method uses 2nd argument to limit the HTML output length, but since the size of original file is passed, it causes unwanted trimming of content.
