[Corrective Sky Surgery Q3]: Incorrect array length returned

Prerequisites

Expected Behavior

Running display(array_length(src)) should return the height of the video/image.

Current Behavior

Correct values are only returned when HEIGHT is set between 300 and 500. For any values <300 or >500, display(array_length(src)) returns 300.

Failure Information (for bugs)

Steps to Reproduce

Run the code in Q3 of the mission: Expected result: 150, Actual result: 300

const WIDTH = 400;
const HEIGHT = 150;

function zoom(factor) {
    
    return (src, dest) => display(array_length(src));
}

install_filter(zoom(2));

set_dimensions(WIDTH, HEIGHT);
start();

Context

• Version used: -
• Browser Name and version: Firefox v93.0
• Operating System and version (desktop or mobile): macOS Big Sur V11.6

I am still able to reproduce this issue. The displayed output does not match the actual canvas dimensions.

Also, the REPL only updates with all the accumulated display values after rerunning the program. I am not sure if this was always the case.
