有没有一种方法可以防止iframe重定向父窗口，但是以这样的方式，即“顶级”重定向仍然在iframe内部工作？ [英] Is there a way to prevent an iframe from redirecting parent window, but in such a way that "top level" redirects still work inside the iframe itself?

So I've read about the HTML5 sandbox property and I understand that if I want to prevent an iframe redirect its parent window I can use the sandbox property leaving allow-top-navigation out. However when this is done, if the iframe was originally relying on top level redirection, what happens in its place is that it redirects to a blank page, effectively breaking navigation.
Can I prevent the iframe from tinkering its parent window while still allowing "top level" redirects, only letting these work within the context of the iframe instead of being top level?
Edit: For context, I'm working with a third party and its page has a form with a target _top. If the iframe is sandboxed, upon submitting the form users get a blank page, if it's not sandboxed the entire page is redirected. I'm looking for something that would allow to submit the form and show the result within the iframe itself.
With HTML5 the iframe sandbox attribute was added.
At the time of writing this works on Chrome, Safari, Firefox and recent versions of IE and Opera but does pretty much what you want:
Allows the iframe content to be treated as being from the same origin as the containing document
<iframe src="url" sandbox="allow-same-origin"></iframe>
