Execution.createComponents handles variable-resolver/function-mapper as if applied on a new page

Currently, the interpretation of variable-resolver/function-mapper and similar will be added to the current page. In additions, it also inherits the varible-resolver that are already defined in the current page.

It is better to be done as if it is applied a brand-new page. Of course, there is some limitation, such as interpreter, since the following event handling depends on it.

Notice that, since some applications might depend on this kind of inheritance, it is better to be done in 5.1.
