Glulx Boxed Quotation - behaviour changed?

I’m trying out Glulx Boxed Quotation by Eliulk Blau, version 2, in Inform 6M62. In a Glulx project. The output doesn’t behave like the example I was trying to copy, which comes from Andromeda Apocalypse.

The issue, as demo’d in my code below, is that once the quote’s been printed, it no longer remains centred if the user resizes the screen. It stays at its absolute position. If any or all of it goes outside the window during the resize, that part is destroyed.

In Andromeda Apocalypse, the quote appears and it stays centred, and doesn’t disappear on a resize. I see that this extension was used by that game, but I know Inform and Glulx Entry Points (the only extension required by Boxed Quotation) have both changed since then.

Could anyone confirm this, or advise on how to get the better behaviour? Thanks.

When play begins:
display the boxed quotation
“And ‘the wabe’ is the grass-plot round
a sun-dial, I suppose? said Alice,
surprised at her own ingenuity.
Of course it is. It’s called ‘wabe,’
you know, because it goes a long way
before it, and a long way behind it –
