If a JQL query has the clause project in ("A", "B"), and a particular user does not have Browse permission on project B, then the query fails with the error "The value 'B' does not exist for the field 'project'".

JQL should rather just return issues from project A for that user. JIRA shouldn't explode just because some issues are hidden.

This is a problem because JQL queries are often reused, eg. on dashboard filters. In my case, projects A and B have a "Pending Approval" status, and I wish to show managers a dashboard of all their "Pending Approval" issues. Because of the above error, this is not possible. project in ("A", "B") fails, as does project != B and any other variant of project mentioning B.
