Configuration property descriptions may be lost when building incrementally

We have two @ConfigurationProperties annotated classes:

package com.example;

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix = "more")
public class MoreProperties {
	
	/**
	 * Another example property.
	 */
	private String someProperty;

	public void setSomeProperty(String someProperty) {
		this.someProperty = someProperty;
	}

	public String getSomeProperty() {
		return this.someProperty;
	}

}

package com.example;

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix = "some")
public class SomeProperties {
	
	/**
	 * An example property.
	 */
	private String someProperty;

	public void setSomeProperty(String someProperty) {
		this.someProperty = someProperty;
	}

	public String getSomeProperty() {
		return this.someProperty;
	}

}

compileJava produces the following metadata:

{
  "groups": [
    {
      "name": "more",
      "type": "com.example.MoreProperties",
      "sourceType": "com.example.MoreProperties"
    },
    {
      "name": "some",
      "type": "com.example.SomeProperties",
      "sourceType": "com.example.SomeProperties"
    }
  ],
  "properties": [
    {
      "name": "more.some-property",
      "type": "java.lang.String",
      "description": "Another example property.",
      "sourceType": "com.example.MoreProperties"
    },
    {
      "name": "some.some-property",
      "type": "java.lang.String",
      "description": "An example property.",
      "sourceType": "com.example.SomeProperties"
    }
  ],
  "hints": []
}

We then change the description of more.some-property to Another example property with a new description.. compileJava now produces the following metadata:

{
  "groups": [
    {
      "name": "more",
      "type": "com.example.MoreProperties",
      "sourceType": "com.example.MoreProperties"
    },
    {
      "name": "some",
      "type": "com.example.SomeProperties",
      "sourceType": "com.example.SomeProperties"
    }
  ],
  "properties": [
    {
      "name": "more.some-property",
      "type": "java.lang.String",
      "description": "Another example property with a new description.",
      "sourceType": "com.example.MoreProperties"
    },
    {
      "name": "some.some-property",
      "type": "java.lang.String",
      "sourceType": "com.example.SomeProperties"
    }
  ],
  "hints": []
}

The description of the property that was not changed, some.some-property, has been lost. Upon running clean compileJava it reappears.

Start by reproducing the issue with the two @ConfigurationProperties classes and the incremental compileJava workflow, then compare the generated metadata before and after changing more.some-property. Check whether clean compileJava restores the unchanged description; done means incremental compilation preserves both property descriptions in the metadata.
