Eclipse WTP shows "Fragment was not found at expected path" for included file from another maven project

I have a simple maven web project composed of two modules (full source code at https://github.com/0xfthul/bug):

• bug-fragment: a web fragment project
• bug-war: a war that tries to include one file from the fragment in index.jsp

Eclipse is showing the following error

Fragment "/included.jspf" was not found at expected path /bug-war/src/main/webapp/included.jspf

screenshot of my eclipse screen, showing the error

When I run this project in wildfly it runs without errors. If I create a similar project without using maven, eclipse shows no error.

While inspecting the error, I've found the following bug report (2013): https://bugs.eclipse.org/bugs/show_bug.cgi?id=398698 The projects available at the bug report are working fine.

Eclipse Version: 2019-09 R (4.13.0) Build id: 20190917-1200

This is content of the org.eclipse.wst.common.component file from the bug-war project:

<?xml version="1.0" encoding="UTF-8"?><project-modules id="moduleCoreId" project-version="1.5.0">

It's a bug. Expect it fixed on the June release, 2020-06.
