kiosk-shell text input

In Weston 11 there appears to be an issue where text input stops working in the kiosk-shell.

The issue can be reproduced as follows:

1. Start gtk3-demo in kiosk-shell
2. Select Entry -> Entry Buffer
3. Type some text.
4. Double click the text, so that it is selected, then drag the selected text with the mouse.
5. Text input no longer works.

This is with Weston 11 kiosk-shell and the patch needed to display anything at all: 341d09d2

The issue does not happen with desktop-shell and also not at all in Weston 10.

Edit a second way to reproduce:

1. Start gtk3-demo in kiosk-shell
2. Select the "Dialogs and Message Boxes"
3. Enter some text in the "Entry 1" input field without having pressed any of the buttons.
4. Press the "Message Dialog" button.
5. Press Ok or Cancel in the Dialog
6. Input to the "Entry 1" input field no longer works.
