I have also noticed this. The way it should work is that, when you tap the screen while inertial scrolling is occurring, the scrolling stops and the item under your finger is not activated. Taps should only activate the selection after scrolling has stopped.
I’ve been having the same issue for a couple of months now. It also doesn’t happen for me when I’m scrolling through playlists. It happens on artist pages and also in my library. I just tested again to see for sure, so I scrolled along a few pages by flicking my finger and tapping the screen to stop the scrolling events. So on any artist’s page, it doesn’t happen if my finger lands on the Shuffle Play button, it doesn’t happen if my finger lands on any of the playlists on the artist’s page, and it doesn’t happens if my finger lands on the See Discography button. On any “Popular Song” or album, it will happen. This doesn’t seem to be happening when I scroll through the contents of any individual playlists though. It also does happen when I go to my library and scroll through all of the songs in my library
