I can somehow understand the reason because there might be people playing around with custom ccs, forget it and later report it as bug.
But come on: Hard blocking people reading simple bug descriptions just because simple CCS improvements for few games are used is way to harsh. I usually need to copy the bug link, go anonymous just to read it and ofc I can't comment any bug without removing for some time my custom ccs.
This is what you get when you use BGA feature custom CCS and try to access any bug: https://imgur.com/a/rf7stJW
(btw. I know I can use custom css with browser addons but I like the ingame feature works also on mobile!)
