Description

I found a weird problem with the import/default rule. See this minimal gist

I import two modules which are very similar, both being CJS with default export.

import ecmaScriptLiteralLoader from 'rdf-loader-code/ecmaScriptLiteral.js'
import ecmaScriptModuleLoader from 'rdf-loader-code/ecmaScriptModule.js'

The first is fine but the second triggers a rule

3:8  error  No default export found in imported module "rdf-loader-code/ecmaScriptModule.js"  import/default

Contributor guide

Research direction
Investigate how the import/default rule resolves default exports for CJS modules that use dynamic imports. Check the resolution logic in the rule implementation and consider the interaction between CJS and ESM.
