TAB indentation in Javascript editor

I am using the latest Eclipse 2025-06 (4.36.0), Build id: 20250605-1316
The used download is "for Java Enterprise and Web Development", though stripped some unwanted plugins.

Wild Web Developer HTML, CSS, JSON, Yaml, JavaScript, TypeScript, Node tools 1.3.10.202502071606

I am using "Generic Code Editor" for my .js files to open with. Accoding the "that internet" it is using the Wild Web Code Editor, if the plugin is installed.

If I edit my code and have two indented lines of code with an empty line between them and hit TAB while the cursor is in that empty line, the indentation is removed. I don't want that. Either I want no advanced logic at all here or the line should be indented up to the level of the previous line (like it is done in Java).

And what is even worse is, that if I paste some code in a JS file, all the root level indentations are removed. I really don't want that.

Where can I configure (that bug away)?

Comienza reproduciendo el comportamiento en el Generic Code Editor con un archivo JavaScript: pulsa TAB en una línea vacía entre líneas con sangría y, después, pega código con sangría de nivel raíz. Rastrea el manejo de la sangría y del pegado del editor; se considera terminado cuando se conserva la sangría de la línea vacía según lo solicitado y no se elimina la sangría de nivel raíz del código pegado, o se identifica la configuración relevante.
