“internal function” within “fx:Component” is accessible but is displayed as an “inaccessible method” and is not suggested.

This is the source code. It builds and runs, but the editor displays it as PROBLEMS.

Start by reproducing the source shown in the issue in Visual Studio Code and inspect the language-server diagnostics for fx:Component. Trace the accessibility check and completion suggestion behavior from the relevant language-server entry point. Done means the valid internal function is no longer reported as inaccessible and is suggested by the editor.
