Bug: load cannot be invoked on a path unless require has been called on it first

[AndyObtiva]

Describe the bug

I cannot use load to load files from a gem unless I have called require on them first. This differs from Ruby behavior where I can call load on any Ruby file the first time.

Opal version: 1.8.2

To Reproduce

Code like this does not work if the file hasn't been required.

load 'path/to/unrequired_file.rb'

For example, if I replace the contents of this file https://github.com/AndyObtiva/sample-glimmer-dsl-web-rails7-app/blob/master/app/assets/opal/sample_selector.rb with the code below, it does not work:

require 'opal'

require 'glimmer-dsl-web' # does not load samples
load 'glimmer-dsl-web/samples/hello/hello_world.rb'

It fails with an error:

runtime.source.js:1958 Uncaught LoadError: cannot load such file -- glimmer-dsl-web/samples/hello/hello_world
    at Opal.send2 (runtime.source.js:1958:1)
    at Opal.send (runtime.source.js:1946:1)

    at Opal.yieldX (runtime.source.js:1734:1)
    at $call_proc (proc.source.rb:45:1)
    at Function.$$call (proc.source.rb:54:1)
    at $$1 (listener_proxy.source.rb:38:45)

    at HTMLAnchorElement.dispatch (jquery.source.js:5430:1)
    at elemData.handle (jquery.source.js:5234:1)

If I do this, it works:

require 'path/to/unrequired_file.rb'
load 'path/to/unrequired_file.rb'

Like updating the example above with this code:

require 'opal'

require 'glimmer-dsl-web' # does not load samples
require 'glimmer-dsl-web/samples/hello/hello_world.rb'
load 'glimmer-dsl-web/samples/hello/hello_world.rb'

This breaks Ruby expectations because in Ruby, I can load a file the very first time without having required the file first. This enables me to build an app that dynamically loads files based on user choices. I use this approach in desktop sample runner apps, and I tried using the same approach in this Opal app: https://github.com/AndyObtiva/sample-glimmer-dsl-web-rails7-app . Right now, because of the error I get, I am forced to track if a file has been required first, and if not required, then I call require the first time. Afterwards, I call load on subsequent times.

I think this needs to be fixed to give us the same behavior we expect from Ruby.
