Here’s the code I used in Obsidian:
[Created TK notes](obsidian://search?vault=Vault&query=file:(TK))
I turned off all other plugins and snippets but the issue persists. Looking at it with the inspector, it points towards this line:
a[href*="obsidian://search"] {
background-image: url(data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 1…,30,30S58.6,70,42,70S12,56.6,12,40S25.4,10,42,10z'%3E%3C/path%3E%3C/svg%3E);
}
