Bug 358096

When I use the "Next Editor" command and hold the Ctrl key to keep its modeless "Editors" dialog open, other elements of Eclipse can also open modeless dialogs that can interfere/overlap with it.  

For example, when holding Ctrl and floating over a method name or field name, you can get a simple modeless dialog that offers functions like "Open Declaration" and "Open Return Type".  

But, when the Editors dialog is open (held open by the Ctrl key held down), and the mouse is floated over a field, both the Editors dialog and the offers dialog will be displayed with the offers dialog on top.  

This can lead to odd/confusing scenarios where the user holds open the "Editors" dialog, sees a window name and moves his mouse to click it.  But during the move, at the last moment, floats over a field or method in the current editor and gets its offers dialog.  Then, before the user realizes the change, he clicks, and fires the offer rather than switching editors.

I believe there would be at least three classes of modeless dialog:  dialogs that get exclusive access to the desktop, dialogs that can coexist other dialogs but can also be suppressed/dismissed by others, and dialogs that are informational (like tooltips) that can always be displayed but should stack appropriately with higher priority dialogs so as not to occlude them.  

I think Next Window's "Editors" dialog is one of those exclusive dialogs, and the correct behavior should be that when Editors is open, it should suppress other competing modeless dialogs from opening.

Reproducible: Always

Steps to Reproduce:
1. Open multiple editors.  Have the current editor be a Java file that fills the window with method calls and field accesses.
2. (Assuming default keybinding for Next Editor is Ctrl+F6) Hold Ctrl and press F6 to pull open the Editors dialog.
3. Continuing to hold ctrl down, float your mouse over a field or method.  The field or method's offers menu dialog should appear along with the Editors dialog!  If the field or method is sufficiently close on the screen to the Editors dialog, its offer dialog will overlap the Editors dialog.
