Apply css fiter causes the position:fixed child(button) become relative.
Code: Select all
:root {background-color: #fefefe; filter: invert(1) hue-rotate(180deg);}
Code: Select all
const btn = document.body.appendChild(document.createElement("button"));
btn.textContent = "📌";
btn.style = "position: fixed; z-index: 1; top: 20px; left: 20px;";

Please be less minimalist in your reporting. We can't do anything with this without having to guess 80% of what you mean.

Confirmed.
Indeed, "html { filter: blur(1px); }" works differently in MS Edge.
However, "body { filter: blur(1px); }" works equally wrong.
Code: Select all
<html>
<head>
<style>
html { filter: blur(1px); }
</style>
</head>
<body>
<button type="button" style="position:fixed;top:20px;left:20px;background:red;";>test</button>

Ah, that's it...
" ...results in the creation of a containing block for absolute and fixed positioned descendants
unless the element it applies to is a document root element in the current browsing context."
This is not a specification, but rather a set of exceptions to the rules. I’ve been saying for a long time that this technology needs to be thrown into the trash and something solid and beautiful should be invented in its place.

Strange thing is current chrome and firefox seem not affect by this anymore.
Just like the drag event, current chrome and firefox can fire dragend normally without set event.dataTransfer.setData in dragstart event(not like MDN said) but pale moon wont.
