This is Brave Version 1.42.88 Chromium: 104.0.5112.81 (Official Build) (x86_64) running on MacOS Catalina 10.15.7
I'll restart my browser and see if it persist....
On restart, Brave updated to Version 1.43.93 Chromium: 105.0.5195.127 (Official Build) (x86_64) and now the blocks appear in yet different places
so weird...
