# Example

This is due to the .popover.hover-popover > .markdown-embed .mod-header + div > *:first-child selector which sets margin-top: 0. However, the first-child selected here is the frontmatter with display: none; and therefore has no effect. If we use the below snipped the issue is fixed.

.popover.hover-popover > .markdown-embed div > *:not([style*="display: none"]) {
    margin-top: 0 !important;
}
