/*
Consistent placeholder styling, introduced to allow us to style the
Reply box like a placeholder.  Chrome uses color to set placeholder,
while Firefox uses opacity, so we need to set both properties to avoid
mixed styling.

While we usually prefer opacity for text color in Zulip, there's some
evidence Edge may have bugs in its handling of placeholder opacity
