@sneak@Gargron@mastodon.online I can read this but the code is definitely not colored like that by our CSS - it appears white as it is supposed to on FastMail's web client. It's the e-mail client trying to do something "smart" here.
@Gargron@Gargron i am aware of all of these mitigations. my point was that if you test your emails on even one device, it should probably be the stack that triggers this bug. it is literally the most popular email client in the world. if it has a bug displaying your message, the message probably needs to be updated. them's the breaks, i don't like the cupertino hegemony either.
also i didn't even realize at first there was text in the box to be copied.
