I am using Chrome v104 and I've noticed this problem over many releases. I set several breakpoints in the debugger. They show properly in the panel docked to the right under breakpoints. They also show properly at first with a blue arrow over the line number in the source code and the line is highlighted green when it stops on it. When I run the code the second time, it stops on the breakpoint and highlights the line in green, but the blue arrow is missing. I cannot tell visually as it steps thru the source code what lines have breakpoints set. I have to look over to the right panel to see what breakpoints are set.
A minor annoyance but it has been happening since roughly v89.
Thanks
