freeze drawn in wrong spot when scroll position isn't 0

Repro steps

I reproed this on Boxer 3.4.19 2024-06-24

1. Download, unzip, and open freeze position repro.box.zip
2. Ensure your window is sized such that there's a vertical scrollbar
3. Vertically scroll down a bit while keeping the line that begins with clear-background ... in view
4. Evaluate the line clear-background cs pd forward 100. It draws a vertical line.
5. Evaluate the line freeze. It freezes the vertical line into the background.

Expected result: The vertical line is rendered at the same exact coordinates before and after freeze is run

Actual result: freeze causes the vertical line to be rendered at a different Y coordinate. Screenshot:
