Steps to Reproduce:

1. Open a TypeScript file.
2. Type vscode.window. and open suggests and details with Ctrl-Space
3. The header of the details widget of a suggest
   vscode.window.onDidChangeActiveTerminal is not word-wrapped.
4. If we want to see the whole header, we have to make the detail ridiculously wider.

Does this issue occur when all extensions are disabled?: Yes

Still not enough wide.

That's on purpose. You can read more here: #99370 (comment). In short, we auto wrap unless the extension provided multiples lines for the details in which case we don't auto wrap so that we don't interfere with its "ascii art". Tho, we might wanna extend that to says "contains new lines and leading whitespace"

[jrieken]

Done. The details/header will now "break to fit lines" unless the extension provided new lines followed by intentation.

I think this change broke the fix for the problem I mentioned here: #29126 (comment) where linebreaks from the extension aren't shown like they should.
