Confirmation dialog buttons stay inside the dialog

In a confirmation dialog, a row of buttons with long labels could run past the dialog's right edge. It showed most in French, for example in the unsaved-changes dialog of the agent editor and the site settings (Quitter sans enregistrer, Rester, Enregistrer et quitter).

The dialog now widens to fit its buttons on one row, up to 80% of the window. On a narrower window, the buttons wrap onto a second line instead. Other dialogs keep their width, and their buttons wrap the same way when the row is too long.

Nothing to change on your side.
