Grid Editor does not save changes when pressing enter after it was opened programatically.

I am using Grid Editor and am opening the editor not via the standard double click, but via an external button (or context menu plugin it does not matter), by calling

grid.getEditor().editRow(rowIndex);

When I change the content in some column (I am using TextField) and then press enter I would expect my changes to be saved. However, the changes are restored to their original value if I edit and hit enter relatively quickly. When I wait a short moment before pressing Enter or if I open the editor via double-click the editor behaves as expected.

To reproduce this it is best to focus the text field programmatically when the editor opens, so you can type the new value and hit enter without moving the mouse. I have slightly modified one of the existing test cases here: https://github.com/teltopr/framework/commit/70b3d060a71b2019811a0e50217ca7a628ab7525

When you run this UI you can click 'Add' to add a new row, then 'Edit' which will open the editor and put the focus on the textfield in the 'Value' column. Quickly type something and hit enter and your changes will be dismissed instead of saved.

• Vaadin Framework version (e.g. 8.5.1 and recent master)
• Chrome 68

Start with the existing Grid Editor test case and the programmatic grid.getEditor().editRow(rowIndex) path described in the issue. Reproduce the failure by focusing the TextField, changing its value, and pressing Enter quickly; done means the edited value is saved rather than restored.
