Question, is this a fix for this issue I just opened up? brave/brave-browser#29074 I am trying to find the source for why it was decided to change the keyboard shortcut to "copy clean link" automatically for users, this is a major regression as it disturbs the actual functionality of using copy/paste, thanks!
