Ladybird: RequestServer going down when trying to write to output stream

[nullishamy]

Talked about it a little on the Discord, but when attempting to navigate to e.g my website (https://amy.is-a.dev), the RequestServer goes down (and subsequently so does Ladybird). Backtrace is here https://gist.github.com/nullishamy/3ad4aaeda44557a9adc18156192627f5. Title is my best-effort guess from reading the backtrace, feel free to edit!
