Steps to reproduce:
Visit https://jsbin.com/jaxixif/1/edit?html,output
or use the following code (also attached):
<!doctype html>
<html lang="en">
<head>
<style>
dialog svg { padding: 2px; }
</style>
</head>
<body>
<dialog>
<details>
<summary>Click this to see the bug</summary>
<svg version="1.1" xmlns="http://www.w3.org/2000/svg"
role="img" viewBox="0 0 100 10" id="graph">
</svg>
<div><b></b></div>
</details>
</div>
</body>
</html>
<script>
tickingCountdown = setInterval(() => {
// we set the textContent. We don't add to it.
document.querySelector("b").textContent = "watch the dialog grow!";
}, 1000);
document.querySelector("dialog").showModal();
</script>
and click the summary to open.
Actual results:
Every tick of the interval, the dialog grows by a small amount.
This doesn't happen if the (empty) SVG is not present, and it doesn't happen in Chrome, so I think it's some sort of layout bug.
Expected results:
This expanding shouldn't happen!

A video is attached demonstrating the "growing".

As a data point, putting the <svg> inside a <div> seems to fix this, although I have no idea why.

The Bugbug bot thinks this bug should belong to the 'Core::SVG' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

It seems something about SVG intrinsic sizing is wrongly stateful.
Looks extremely suspicious (from bug 1162418).
