Line breaks from textarea fields gone in emails

Hi there, using 1.15.9.

It seems that line breaks from textarea fields are being eaten in notification emails – both the “enters” and “shift-enters” are being replaced by a space in the email, resulting in a single line. Which is suboptimal, to say the least.

I tested it both with the manual tag {textarea-1} as well as {all_fields} – the result is the same. I also tried removing all the “advanced” options from the Add Email Notification window, just in case.

I could’ve sworn it worked previously – did one of the newer updates break something?
