In T315605 there was .noexcerpt added to all Phonos outputs. However, on some wikis, e.g. plwiki audio templates are used in a way that expects that the label is in fact rendered in page preview. See https://pl.wikipedia.org/wiki/Wikipedysta:Msz2001/Lech_Wa%C5%82%C4%99sa for an example of such a lead with an excerpt that would be generated for it. Currently the audio template had to be hacked so that the preview is generated correctly.
We don't display IPA in Polish, because the way you write something almost directly implies the way it's read (unlike English), so the player put directly in the article subjects that must be visible in a page preview.
After switching the template to Phonos, page preview is rendered incorrectly as: " – polski działacz związkowy i polityk", without the subject before the endash. This makes inline Phonos unsuitable for such use cases.
Therefore, I'd like to recommend an option in Phonos tag that configures whether or not to use the noexcerpt CSS class.
The original article which was used as an example is https://pl.wikipedia.org/wiki/Lech_Wa%C5%82%C4%99sa for example (excerpt can be seen here: https://pl.wikipedia.org/api/rest_v1/page/summary/Lech_Wa%C5%82%C4%99sa - it's correct due to hacks in https://pl.wikipedia.org/wiki/Szablon:Wymowa).
