Link with editor does not work in Project Explorer when project presentation is "hierarchical"

[Kiiv]

Following #819

Steps to reproduce

From a fresh installation and clean workspace:

In Project Explorer, ensure "Link with Editor" is enabled.
In Project Explorer, double click to open a project.
Use the open resource dialog (shift+⌘+r) to open src/main/java/com/example/package1/File1.java
Use the open resource dialog to open src/main/java/com/example/package2/File2.java
Use the open resource dialog to switch back to File1.java, and note the link with editor functionality isn't working.
Use previous (fn+control+up arrow) and next (fn+control+down arrow) tab shortcuts to switch between open files, and note the link with editor functionality isn't working.
Click on the open tabs one at a time, and note the link with editor functionality isn't working.
In Project Explorer, manually expand the tree until you can see the contents of package1 (but not package2).
Repeat steps 5-7, and note that the "Link with Editor" is working when the tab for File1.java is active (but not File2.java).
In Project Explorer, manually expand the tree until you can see the contents of package2.
Repeat steps 5-7, and note that the "Link with Editor" is working with File1.java and File2.java.
