Breakpoint is not (visually) moved when on commented line.

Steps to reproduce:
1. Open or create a project with some code.
2. Set a breakpoint on a commented line (or comment a line where you have set a breakpoint)
3. Debug

Expected results:
1. The breakpoint marker is moved to the next active line of source code below the commented line.
2. Execution is halted at the line the breakpoint was moved to.
3. The breakpoint is moved back to the commented line when debugging stops.

Actual results:
1. The breakpoint marker is not moved.
2. Execution does stop at the line that the marker should be moved to, so the functionality of the debugger actually works, so this is just a problem with the marker in UI not getting updated.
