Yes, this is an issue and not a feature request.
Every single human I personally know who uses Cubase gripes about this, as well as a huge amount of people on the forum. This has been requested for such a long time yet refuses to be fixed: Let us have the option to disable activating Loop in the Ruler. I’ve been using Cubase for many years and I still activate loop accidentally all of the time in the ruler – these are the little things that can make working fast on Cubase a chore instead of a smooth joy. No other DAW I’ve used has it like this for a very great reason. I’m sure it had a good intention behind it, but at least let us turn it off.
I’m begging you. Truly, begging. Thank you for listening and implementing this now.
