env(safe-area-inset-top) incorrectly resolves to 30px in non-fullscreen mode
Bug #1333:
env(safe-area-inset-top) incorrectly resolves to 30px in non-fullscreen mode

Description
In non-fullscreen mode, the browser reports "env(safe-area-inset-top)" as "30px", while the same page reports "0px" in fullscreen mode.
This causes an unexpected 30px top inset in web applications that use the safe-area API.
Reproduction
<!doctype html>
<html>
<head>
<meta name="viewport"
content="width=device-width, initial-scale=1, viewport-fit=cover">
<style>
#test {
padding-top: env(safe-area-inset-top);
}
</style>
</head>
<body>
<div id="test">Test</div>
<script>
console.log(getComputedStyle(document.querySelector('#test')).paddingTop
);
</script>
</body>
</html>

Actual
Non-fullscreen: "30px"
Fullscreen: "0px"
Expected
"env(safe-area-inset-top)" should reflect the actual safe-area inset and should not report "30px" when there is no corresponding unsafe area.
