7 years ago 2 problems I noticed: It's not possible to set a custom background color for the body tag and the size of h1..h6 are all the same. It's not even possible to overwrite the injected CSS with "!important", I guess that's just the way the preview component from VSCode works.
From what I understand in the code, the reasoning for adding it was some display problems of the preview. I checked if there where still display problems and couldn't find one. As the extension is a little older now, I suspect that those problems are gone in newer versions of VSCode - which makes sense as they are using a way newer version of Electron and fixed so many stuff.
You might check this first for yourself if you remember any specific problems.

Previously, it wasn't possible to override the styles that where injected through the custom stylesheet.
