Can someone explain why "preserve bubbles" is missing from the UI in the particlefluidsurface node in H 18.5 (563)?
It was there in 2020 still according to the screenies in this thread:

This is a screenie from yesterday:



The parameter is there in the UI editor and is not hidden.
Is it in any way conditional? The docs don't say anything. Mysteriouslier...

That parameter Preserve Bubbles is set up to hide when the Method parameter is set to its default option, Average Position. When the Method is changed to Spherical, then the Preserve Bubbles parameter is made visible. The conditional for the Preserve Bubbles visibility is noted in the Hide When field of the Edit Parameter Interface screenshot.

Oh, thank you. I wish the manual was as clear as you, and I wasn't as blind as a mole
