createScriptLoader causes rootless resource error

[apatrida]

Describe the bug

In createScriptLoader the following code:

 setTimeout(() => spread(script, scriptProps, false, true));

causes a warning about doing reactive things outside a root not disposing of resources. Changing to:

 setTimeout(createCallback(() => spread(script, scriptProps, false, true)));

removes the warning.

We specifically added the timeout to move the call of spread out of the context, as otherwise hydration breaks. Can you please test your fix in a solid-start app with SSG+hydration?
