"Save for web (Legacy)" no longer clips to visible artwork

UPDATE:

I completely uninstalled Illustrator, made sure all Windows 10 updates have been installed and rebooted my computer. I then reinstalled Illustrator, starting with version 24.0, and then updated to each successive version. Results of incremental install and updates:

• Version 24.0 --PASSED -- traditional functionality experienced
• Version 24.0.1 -- PASSED -- traditional functionality
• Version 24.0.2 --PASSED -- traditional functionality
• Version 24.1 -- FAILED -- no longer clips to visible artwork as it should
• Version 24.1.1 -- FAILED -- does not clip to visible artwork as it should

Right now, as far as I see, I cannot reproduce the (mis)behaviour you are describing.

What OS are you using? And is it the most current version of Illustrator?

As always, providing a sample .ai file may help to understand the issue. Can you share one?

I don't use the latest version of AI so can't test the possible bug. I use the "ImageCapture" Javascript method to save PNGs. Maybe this script would help you until Adobe address the issue. It requires items to be unlocked. Could be edited to unlock all visible items.

function save_PNG(dest) {
    var aDoc = app.activeDocument;
    app.executeMenuCommand('selectall');
    app.executeMenuCommand('group');
    var MyOpt = new ImageCaptureOptions;
    var myBounds = aDoc.selection[0];
    myBounds.fillColor = aDoc.swatches[0].color;
    MyOpt.antiAliasing = true;
    MyOpt.matte = false;
    MyOpt.resolution = 300; // screen PPI  
    MyOpt.transparency = false;
    try {
        var Filename = new File(dest);
        aDoc.imageCapture(Filename, myBounds.visibleBounds, MyOpt);
    } catch (e) {}
    app.executeMenuCommand('undo');
}

var dest = "/Users/aUser/Documents/test.png";//replace with actual path
save_PNG(dest);
