Research direction
Start by locating the NumberTextBox control and the code handling Increment=0.1d with DecimalPlaces=2, then reproduce the arrow-increment case described in the issue. Done means successive increments display 2.30 rather than 2.29, with coverage for the reported floating-point boundary if relevant tests exist.
