CompletionItem.documentation should be plain text
v0.4.0
- in VSCode, create a sample project and do code assist on
package com.aeschli.testapp;
public class TestHelper {
public static boolean compare(String a, String b) {
return a.|
}
}
This shows code assist proposals. Looking at the issue descriptions, they are not correctly rendered.

Unfortunately, CompletionItem.documentation (and details) only support plain text.
On our side, the request to support rich text is microsoft/vscode#11877
