`break` inside `while` loop will execute the `ensure` block outside of the `while` loop

It seems that `break` inside a `while` loop will execute the `ensure` block outside of the `while` loop.
For example:

```ruby
begin
  while true
    puts 1
    break
  end
ensure
  puts 2
end
```

mruby (master) will output:

```
1
2
2
```

While Ruby 3.3 will output:

```
1
2
```
