3d object rendered difference from mac version

OpenSCAD mac version

OpenSCAD WebAssembly version

I have been doing a bit of testing. I noticed there is a difference between OpenSCAD Mac desktop version vs WebAssembly version. See images above.

Is this expected? My OpenSCAD code below:

// Parameters
length = 18 * 25.4; // Convert inches to mm (18 inches)
outer_diameter = 25; // Approximate outer diameter in mm
inner_diameter = 20; // Approximate inner diameter in mm
corrugation_depth = 2; // Depth of corrugations
corrugation_width = 5; // Width of each corrugation
num_corrugations = length / corrugation_width; // Number of corrugations

// Corrugated hose
module corrugated_hose() {
    difference() {
        // Outer corrugated surface
        for (i = [0 : num_corrugations - 1]) {
            translate([0, 0, i * corrugation_width])
            cylinder(h = corrugation_width, d1 = outer_diameter, d2 = outer_diameter - corrugation_depth, $fn = 100);
            translate([0, 0, i * corrugation_width + corrugation_width / 2])
            cylinder(h = corrugation_width, d1 = outer_diameter - corrugation_depth, d2 = outer_diameter, $fn = 100);
        }
        // Inner smooth surface
        cylinder(h = length, d = inner_diameter, $fn = 100);
    }
}

// FIP connectors (simplified)
module fip_connector() {
    cylinder(h = 10, d = outer_diameter, $fn = 100);
}

// Assembly
translate([0, 0, -5]) fip_connector();
corrugated_hose();
translate([0, 0, length + 5]) fip_connector();

Likely caused by the experimental feature "lazy-union". This one is unstable and not generally recommended to be enabled.
