When:

• a custom field is restricted to a particular project
• The custom field is added as a column to your issue navigator
• You search across "All projects"

The custom field column does not display.

If you then manually highlight all projects in the list, the column does display.

This is inconsistent. Surely selecting "All projects" should behave the same as manually selecting all projects?

In both cases, the behaviour should be to show the custom field columns.
