Manual: Fix links of primitives page.

[taenykim]

Fixed #24025

Description

An error occurred when clicking on Box Geometry because it creates another panel within the iframe.

The location is different between docs and manual, so I think there will be a lot of side effects. So I modified it to replace the parent page if the HTML is loaded within the iframe.

I would appreciate it if you could let me know if there is another good way.

Thanks to the kind document, I am having fun studying threejs

How about we use the same approach like when linking from the docs to the examples? Meaning the site is opened in a new tab.

In this way, the issue can be fixed in the manual without touching the docs. It should be sufficient to add the following line:

a.setAttribute('target', '_blank');

at this place:

three.js/manual/resources/threejs-primitives.js

Line 709 in fff7be3

const a = document.createElement('a');

The solution you suggested is better. 😄 I modified it
