It might be because you're using a custom content (CC) skin overlay? Also, your Sim's eyes barely squint when they smile, compared to the Sim in the original post. When my Sim smiles without squinting, the eyelashes stay in place too.
By the way, there are no issues in CAS — the problem only appears in live mode.

So here I am back as promised with my new results. I can now see what you see. I tested with a brand new Sims 4 vanilla game. The Sim I used was the first one the game gave me. This one has a different eye shape, which shows the problem much more clearly than a Sim with an average eye shape. Best to see if you let a sim use the mirror and order him/her to fresh-up. So yeah, "Me too"
