Start by reproducing the reported cdk-virtual-scroll-viewport example with Angular CDK 14.2.7 and compare its .cdk-virtual-scroll-spacer height with version 14.0.3. Trace the virtual-scroll viewport and spacer behavior to identify the regression; done means scrolling to the end no longer creates an excessive blank space and the spacer height is correct.
