the guy at android feedback is not seeing the issue either, so far. can you please view the attached test file which I just made & sent him, & tell us what you see.
My observations follow:
I put copies of this simple 3 paragraph test “book” onto my Kobo arc tablet ( running v5.5 of kobo reader) and onto my Kindle Fire HDX ( running v 5.4)

In 5.5 I see para 3 is spaced a little larger than para 1 but clearly not as wide as para 2.

In 5.4 para 3 is if anything a tad more widely spaced than para 2.

This observation holds for all 3 available fonts and across all font sizes.

So the new rendering engine in v5.5 of the kobo reader app is rendering differently, in the absence of para-specific line height declarations.

I will put this on MR forum in the hope of attracting more comment & more testers.

As an aside, FWIW, in the moon + reader on those 2 tablets, all 3 paragraphs display identically. That is good in one sense, all 3 paragraphs are very "readable" but it suggests that the moon reader app does not honour all original css, which is not a “feature” that I approve of

PS I cannot get my head around how the android OS on Kindle, which after all is mostly vanilla Android, would/could interfere with how text is rendered. surely the app has complete control over what appears on the screen, all that Android does is force the ugly pair of thick bars onto centre foot of screen display , so that there is an exit-full-screen-mode facility ( as another aside, it does not force those 2 bars into the kindle reader app display, the kindle is allowed 100% full screen - , but I see no way to stop it happening in moon reader, kobo reader... )
