Nested Partials Ignore Append Mode When Parent Partial Uses Replace Mode

[guitavano]

As I have replace default at parent Partial, the "append" inside is being ignored and replaced too.

If I have:

<Partial name="modal">
    <p>example</p>
    <Partial name="modal-content" mode="append">
      <p>here is cool content</p>
    </Partial>
</Partial>

And fetch a page with:

<Partial name="modal">
    <p>example 2</p>
    <Partial name="modal-content" mode="append">
      <p>second cool content</p>
    </Partial>
</Partial>

I expected that parent partial replace the content and nested partial append, new page like:

<Partial name="modal">
    <p>example 2</p>
    <Partial name="modal-content" mode="append">
      <p>here is cool content</p>
      <p>second cool content</p>
    </Partial>
</Partial>
