This is definitely a bug - or maybe several bugs:

1. In ODF: since PowerPoint seems to not support the pause option in
presentations, it simply ignores any value set in presentation:pause attribute
[1], and doesn't write it back to ODF. But LibreOffice treats the missing
attribute as its "default" 10 s, which is incompliant to the standard which
requires that missing attribute be treated as if 0 s pause duration was set.

2. In external formats (namely, PPT), it introduces the (default) delay of 10 s
absent in the PPT.

The problem is likely remedied simply by replacing the default of 10 s by 0 s
in PresentationSettings::PresentationSettings() [2].
