Map<K,V> with escaped key not works properly in application.yml

[musashi-miyamoto]

Describe the bug
If map key is escaped string (like [/**]), VSCode YAML code completion not works properly.

To Reproduce

• Windows 11 23H2 (Build 22631.3447)
• OpenJDK 21.0.2
• Spring Boot v3.2.5
• VSCode v1.88.1
  • Language Support for Java(TM) by Red Hat 1.30.0
  • Spring Boot Tools v1.53.0

Sample configuratin class:

@ConfigurationProperties(prefix = "demo")
public class RootConfig {
    private Map<String, ChildConfig> pathMap;
    // Getters and Setters...
}

public class ChildConfig {
    private String host;
    private int port;
    // Getters and Setters...
}

Key without escape works properly:

Key with escape provides no completion:

Requires one extra deeper indentation:

Completion provides no host, used in previous key:
