Wrong evaluation of {project.artifactId} variable in child POMs if included in <url> element

Suppose you have the following snippet in your parent POM:

...
<artifactId>parent</artifactId>
...
<url>https://intranet.xy.sk/javaweb/${project.artifactId}</url>
<distributionManagement>
	<site>
		<id>site-server</id>
		<name>Site Server</name>
		<url>https://intranet.xy.sk/javaweb/${project.artifactId}</url>
	</site>
</distributionManagement>
...

Then 'mvn help:effective-pom' command for this project will produce correct URL values:

• <url>https://intranet.xy.sk/javaweb/parent</url>
• <url>dav:https://intranet.xy.sk/javaweb/parent</url>

But, if you create a child project that declares above defined POM as a parent (and does not explicitly specify its own <url> or <distributionManagement> sections, i.e. it should inherit these sections from parent), the output from 'mvn help:effective-pom' command will contain wrong values:

• e.g. for the child POM with artifactId = 'child', the output is:
  • <url>https://intranet.xy.sk/javaweb/child/child</url>
  • and <url>dav:https://intranet.xy.sk/javaweb/child/child</url> in 'distributionManagement' section.
    • I think correct output should end only with one 'child' at the end of the url as follows: https://intranet.xy.sk/javaweb/child
• and if you have a sub-module 'grandchild' of this child project, which also defines this 'child' artifact as its parent, the output is:
  • <url>https://intranet.xy.sk/javaweb/grandchild/child/grandchild</url>
  • <url>dav:https://intranet.xy.sk/javaweb/grandchild/child/grandchild</url>
    • The correct output should be: https://intranet.xy.sk/javaweb/child/grandchild
