Custom <a> links are not clickable in the editor

[ClementEXWiki]

Describe the bug
Creating a custom inline content that renders to an <a> element, the link is visible and styled, but not clickable. Clicking on it simply places the cursor inside the link, and nothing else.

To Reproduce

1. Create a custom inline content spec rendering to a simple <a href="...">...</a> element
2. Insert it into the editor
3. Click on the link in the editor

Note that adding target="_blank" doesn't solve the issue. Mimicking BlockNote's own link HTML structure doesn't work either, which leads me to think the editor adds an click listener to these ilnks.
