Current Behavior

When setting a tooltip in the sidebar (e.g., node configuration panel), the tooltip renders
as a literal string instead of interpreting it as a line break.

Example of what is shown in the UI:

Invalid properties:<br> - logonType<br> - maxConnections

Instead of rendering as:

Invalid properties:
- logonType
- maxConnections

Current Behavior:

Tooltip only accepts plain strings.

Content is rendered using text() (likely for security reasons).

As a result, HTML tags such as <br> are displayed as literal text.

This causes formatting issues in the sidebar where multi-line messages are needed.

So i see from code in packages/node_modules/@node-red/editor-client/src/js/ui/tab-config.js:213
that it's sending <br>.

I could create a pull request but need to know the appropriate path for the fix (instead of br we can simply use , for multiple fileds)

Expected Behavior

Invalid properties:
- logonType
- maxConnections

So Tooltips should either:

Support safe multi-line rendering (e.g., converting \n to line breaks), or

Allow limited/sanitized HTML such as <br>.

Steps To Reproduce

modify any configuration node that has more than 1 validation and make both fields invalid and check sidebar Configuration node tab
