Templates in included pages not evaluated in some cases

[mjf]

SilverBullet version: 0.9.4

When a page containing some template is included with ![[page]] in another one, the templates are not evaluated in some cases. The following works well:

/page/included

This is a page to be included in another one.
```template
{{1+2}}
```

/page

This is the page that includes the other one.
![[/page/included]]

But I have a table in the included page where I summarize a table column using custom space script sum() function. For some reason, if that page is included into another the summation does not work and results in value 0 in the including page. The included page, if viewed, works as expected.

silverbullet.registerFunction({name: 'sum'}, (key, items) => {
  return items
    .map(i => parseFloat(i[key]))
    .reduce((acc, n) => acc + (isNaN(n) ? 0 : n), 0);
});

/page/included

cost | remark
-----|-------
1    | foo
2    | bar

```template
Total: {{ sum( 'cost', { table where page = @page.name }) }}
```
