After updating Servo's embedding API, servoshell can now display favicons for different tabs!
It's a small thing but it makes the browser feel much more complete.

I tried Servo, the undercover web browser engine made with Rust
Servo was supposed to be Firefox's future. Now it's an independent effort to make a fast and secure web browser engine.

OK, this is wild.
In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.
It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.

It may not look like much, but it makes custom elements in servo significantly more powerful :D
