Description
Context:
- Playwright Version: v1.10, v1.9.x
- Operating System: Windows 10 64bit
- Node.js version: 14.16 (not relevant for this bug)
- Browser: Firefox

Describe the bug
The bundled firefox version (firefox-1238, and earlier) crashes when using a SVG favicon:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link rel="icon" type="image/svg+xml" href="/favicon.svg">
<title>SVG ICON TEST</title>
</head>
<body>
NO TEXT
</body>
</html><svg width="32" height="32" viewBox="0 0 32 32" xmlns="http://www.w3.org/2000/svg">
<style>
@media (prefers-color-scheme: dark) {
.dummy { fill: #f22 }
}
</style>
<circle fill="red" cx="16" cy="16" r="12" />
</svg>Windows event log
Faulting application name: firefox.exe, version: 87.0.0.7746, time stamp: 0x6051c457
Faulting module name: xul.dll, version: 87.0.0.7746, time stamp: 0x6051c464
Exception code: 0xc0000005
Fault offset: 0x00000000034e8512
Notes
- This happens when running the bundled FF instance manually or from PW
- Does not happen with various "stock" FF nightly/beta/release versions
- Reproducible on multiple Win10 machines with different hardware
- Safe mode does not help
- Headless also does not work
- When running manually the cached svg favicon causes a crash when opening history
edit: only crashes with the "prefers-color-scheme" media query, this might be uncommon in favicons - but it does cause a hard crash
