Interesting. So it may be that duplicate keys in ENV in general are in issue? We generally think of ENV having unique keys, but I'm guessing that is not enforced by the kernel.
Looking at the implementation of setenv(3)/unsetenv(3) on OpenBSD, it does specify that that there can be multiple environment entries with the same key, so Ruby's ENV implementation should probably not assume there is at most one entry per key.

Bug #17254: ENV.replace may set nil instead of the proper value
https://bugs.ruby-lang.org/issues/17254#change-88128

On docs.ruby-lang.org, it uses [snap ruby](https://snapcraft.io/ruby), and it failed to run `rdoc`.

I investigate it, it caused by setting nil instead of the proper value in `ENV.replace`.
```
vagrant@buster:/tmp/t$ cat Gemfile
# frozen_string_literal: true
source "https://rubygems.org"
git_source(:github) {|repo_name| "https://github.com/#{repo_name}" }
# gem "rails"
vagrant@buster:/tmp/t$ env PATH=/var/www/docs.ruby-lang.org/shared/bundle/ruby/2.7.0/bin:/snap/bin:$PATH DEBIAN_DISABLE_RUBYGEMS_INTEGRATION=1 bundle exec env -u RUBYOPT ruby -r/snap/ruby/189/lib/ruby/gems/2.7.0/gems/bundler-2.1.4/lib/bundler/setup -e 'p ENV["RUBYLIB"]'
"/snap/ruby/189/lib/ruby/gems/2.7.0/gems/bundler-2.1.4/lib"
```
Calling `ENV.clear` before `ENV.replace` resolves this issue.
```
vagrant@buster:/tmp/t$ cat /tmp/clear-before-replace.rb
class << ENV
alias orig_replace replace
def replace(h)
clear
orig_replace(h)
end
end
vagrant@buster:/tmp/t$ env PATH=/var/www/docs.ruby-lang.org/shared/bundle/ruby/2.7.0/bin:/snap/bin:$PATH DEBIAN_DISABLE_RUBYGEMS_INTEGRATION=1 bundle exec env -u RUBYOPT ruby -r/tmp/clear-before-replace -r/snap/ruby/189/lib/ruby/gems/2.7.0/gems/bundler-2.1.4/lib/bundler/setup -e 'p ENV["RUBYLIB"]'

```
Where should call `ENV.clear`?
In `ENV.replace` or caller of `ENV.replace`?
