aha, so it's not just me! I can confirm I'm experiencing the exact same issue, also on Sequoia 15.7.5 (interesting - I will check out with my Tahoe-running Mac if this is a Sequoia issue) although on an ageing but with dignity Intel MBP Pro circa 2018
Curious to see if it's a Sequoia issue so please let us know? 
P.S. Slowly starting to feel pressure to upgrade to Tahoe sadly. Couple other apps I use will only do future updates on Tahoe and above. I really wanted to wait longer before I upgrade
no, it's the same on the latest Tahoe as well. So don't upgrade to Tahoe, at least not in hope it will fix this!
Can you check whether this behaves correctly for you in 6.523 alpha?
Confirmed it is fixed. Thanks!
