set page rule not working properly with hidden heading

[SkytAsul]

Description

When using show heading: {} to hide headings, they cause weird bugs with set page rules on newly created pages.

For instance :

#set page(width: 5cm, height: 2cm)
#show heading: {}

Page 1 that should *not* have a header.
#pagebreak()

#heading("Random hidden heading")

#set page(header: "This is the header")
Page 2 that *should* have a header.

#pagebreak()
Page 3 that *should* also have the header.

The "Page 2" does not have the header, because the heading kind-of starts a new page without content. The set page rule should automatically break a new page but actually does not.
I don't really understand the internals going on here but I think it's a bug with the compiler.
