Description
What version of Go are you using (go version)?

Does this issue reproduce with the latest release?
I do not know
What operating system and processor architecture are you using (go env)?
go env Output

What did you do?
Training for docker with go, I forked github.com/olliefr/docker-gs-ping and added embed directive
//go:embed foo
var foo embed.FSit worked fined in my working directory.
But when I configured Dockerfile for having everything at root, it did not work.
# Set destination for COPY
WORKDIR /
To reproduce the bug
git clone https://github.com/fullstack-lang/docker-gs-ping.git
cd docker-gs-ping
docker build --tag docker-gs-ping .
What did you expect to see?
a successfull go build
What did you see instead?
> [7/8] RUN go build -o /docker-gs-ping:
#11 2.002 # github.com/olliefr/docker-gs-ping
#11 2.002 /main.go:14:5: embed oo/foo.txt: open /oo/foo.txt: no such file or directory
A workaround is to have the WORKDIR different from "/"
