Losing focus in linked mode after the popup dialog is shown

[mehmet-karaman]

Hi,

It seems that the xtext editors linked mode feature has a small issue, when the user is entering into the rename refactorings editing mode ("Rename Element" context menu).

It happens right after the popup is shown and the user isn't able to continue with editing directly. A Patch is ready, I am going to push it. It would be nice if someone else could test this behavior and my changes.

Thanks in advance.

Best regards
Mehmet
