#1279 Property editing looses value on Linux

[Andras Soltesz]

Case 1: Adding a new property

Context:
- There is no property on the node
- I want to add a property the node

Steps:
I push Alt+F9 on teh node to start adding a property
The property grid gets displayed and the cursor is in the property name cell
I enter the name of the property and push TAB to get to the property value cell

Expected result:
The name of the property remains in the cell and the focus moves to the property value cell

Actual result:
The name of the property disappears from the cell (like I never entered it)
Focus moves to the value cell

Case 2: Editing an existing property

Context:
- There is a property on the node
- I want to change the value of the property

Steps:
I click on the property grid, into the property value cell I want to change
I modify the value of the property
I push TAB to get to the property value cell

Expected result:
The new property value remains in the cell and the focus moves to the next property

Actual result:
The new value of the property disappears from the cell (like I never entered it)
Focus moves to the next property

Summary:

Seems like property editing doesn't handle leaving the cell with the TAB button.

The same works well on MacOS.
