<br> tags no longer working in tooltips in Chrome

Description

The < br > tag used to work fine in the tooltips with the last versions of Chrome (up to the version 136.0.7103.114)

With the last update in Chrome, the < br > doesn't seem to be properly rendered in HTML as it used to. Currently the
gets displayed as regular text in the tooltip.

Apprently the solution provided 2 years ago (https://github.com/mermaid-js/mermaid/pull/3331) doesn't seem to work anymore in Chrome.

Seems to be working properly on Edge and Firefox though.

Steps to reproduce

1. Execute the code in the following codesandbox: https://codesandbox.io/p/devbox/wplvg5
2. Mouse over on a node
3. The text in the tooltip will be displayed with < br >

Not properly rendered anymore in HTML
