Very long topic names were stretching the dimensions of the change metadata section. Configures the maximum width for the label to the same value as the already-established maximum width for the input and sets up styles for text to be "ellipsized" when it exceeds that width. Bug: Issue 4284 Change-Id: I9f787f2e16a302a99c843579f79049750f482438
