[scribus] text-flow gets changed by 1.5.8

Hi,

I've a small Scribus file attached, created using v1.5.5 and harfbuzz 2.6.4
(my LinuxMint VirtualBox).
It contains a simple text where the text box's width is just wide enough
for the text (88.100 mm). If I now open this file in Scribus 1.5.7 and
harfbuzz 3.2.0 (my Gentoo system) it can't render the whole text. I have to
increase the text box's width to 88.500 mm to have the complete text shown.

What makes me think now is why an external library can have that effect on
Scribus layouts. Maybe someone can explain that to me?

Best regards,
Andreas
