Debugger stops only on 1st breakpoint inside a Fiber block and ignores all subsequent ones

[klobuczek]

In ruby 3.1.1 the debugger stops only on 1 line in code like below:

Fiber.new do
   puts 1
   puts 2
end.resume

So if I put 2 breakpoints inside the block at the lines containing puts the 2nd breakpoint is ignored. https://youtrack.jetbrains.com/issue/RUBY-29456
