Can only navigate to process engine in webapps with trailing slash

Environment (Required on creation):

• Tested with the Wildfly distro for 7.16.0-alpha5, but probably any webapp distro

Description (Required on creation; please attach any relevant screenshots, stacktraces, log files, etc. to the ticket):

• The entry URL to an application and process engine must have a trailing slash. Without it, an infinite loading spinner is shown.

Steps to reproduce (Required on creation):

• Navigate to http://localhost:8080/camunda/app/cockpit/default

Observed Behavior (Required on creation):

• An infinite loading spinner is shown
• Browser console says:
