Preseed URL expanding to Buster instead of Bullseye

[john doe <johndoe65534@mail.com>]

Hi all,

I'm installing Bullseye using
debian-bullseye-DI-alpha1-amd64-netinst.iso with a preseed file.
When no path is specified in the preseed file URL, it expands to
'/./buster/preseed.cfg' ant not to '/./bullseye/preseed.cfg'.

Is this a bug or am I missing something?
