Xray: Does JQLIssues count only work with a single project?

[IanPartridge]

I am trying to loop over a query that fetches all the bugs associated with the test executions in an execution plan.  The execution plans are across multiple projects.

This returns the correct number of defects:

${jqlcount: issuetype = "Bug" AND issue in linkedIssuesFromQuery("issue in testPlanTestExecutions(${Key})")}

Whereas this only returns the defects in the project the Test Plan is in, missing out those that are in a separate project.

#{for i = JQLIssuesCount|clause=issuetype = "Bug" AND issue in linkedIssuesFromQuery("issue in testPlanTestExecutions(${Key})")}

${JQLIssues[i].Key}

#{end}

Does JQLIssuesCount only work on a single project?
