Italics are not working for me in my portable text editor using a standard blockContent schema. Bold is working however. Is this happening to anyone else or am I doing something wrong? Code in 🧵

import { defineArrayMember, defineType } from 'sanity'

export default defineType({
    title: 'Simple Block Content',
    name: 'simpleBlockContent',
    type: 'array',
    of: [
            title: 'Block',
            type: 'block',

What version of the Studio are you running?
Sep 27, 2023, 5:38 PM
I’m running:
Sanity Studio version 3.16.7
Latest version is 3.16.7

Very weird. I can see that the data-mark=“em” is being applied in the browser.

My project has an embedded studio in a Next JS 13 app router project, but I have separated the css into route groups. I am using panda css, so it’s a little untested waters in that regard, but I don’t see where any css would be overriding the studio styles. And it’s weird that bold and underline both work in the editor.

My studio app simply follows the Sanity starter template pattern:

Huh, ok I commented out the css in that route that was taking care of the studio #app appearance and it fixed the issue — so obviously I was somehow overriding the italics from the panda css file. Thanks for letting me work this out out loud

For any Panda CSS users out there, this was the solution: remove the reset from Panda and add
margin: 0
on body

@layer base, tokens, recipes, utilities;

@layer base {
    body {
        margin: 0;

    #app {
        height: 100vh;
        max-height: 100dvh;
        overscroll-behavior: none;
        -webkit-font-smoothing: antialiased;
        overflow: auto;
        margin: 0;
