Marketplace entries in Eclipse project page create bogus URL

Summary

The URLs that can be set in the Eclipse project page lead to invalid URLs. For example, this is configured for the WindowBuilder project:

From what I understand, this should create two buttons, one labeled "Latest Version", linking to https://marketplace.eclipse.org/content/windowbuilder and one labeled "Nightly Version", linking to https://marketplace.eclipse.org/content/windowbuilder-nightly-build.

However, this only produces the bogus URL https://marketplace.eclipse.org/content/windowbuilder,%20Latest%20Version,%20https://marketplace.eclipse.org/content/windowbuilder-nightly-build,%20Nightly%20Version.

Note that this issue not only exists for WindowBuilder, but other projects have the same problem, which makes me believe that this is either a gross misunderstanding on how this entry is supposed to work, or a general issue:

• https://projects.eclipse.org/projects/modeling.tmf.xtext
• https://projects.eclipse.org/projects/tools.acute
• https://projects.eclipse.org/projects/technology.rcptt
• https://projects.eclipse.org/projects/modeling.viatra
• https://projects.eclipse.org/projects/tools.buildship
• ...

Steps to reproduce

• Go to an arbitrary project website that publishes their artifacts to the Eclipse marketplace.
• Click on the Marketplace link

What is the current bug behavior?

The link leads to a 404.

What is the expected correct behavior?

The corresponding marketplace entry should be shown.
