Minimal Theme

Hi all,
not sure if this is the right place to mention this, so please excuse me if it’s not.

I’ve recently tried moving a note of mine about the basics of HTML from Notion to Obsidian and noticed something strange (to me at least).

As the note is about HTML, I have lots of code blocks within the note. Now these came across perfectly with a simple copy-paste from Notion, but what’s strange is how these code blocks are rendered in preview mode. In preview mode these code snippets are displayed as clickable tags:

Edit mode

Preview mode
Preview mode

Is this a theme issue or something on Obsidian’s end?

Also, I’m really pleased to see the syntax highlighting in the preview mode - is this a coincidence because its HTML or is this supported in Obsidian? or a theming thing?
