Config is created twice while action is called. Is this by design? #30047

In configuration_helper.rb, available_options are invoked twice (line 4 and 8). We know that available_options is an array containing ConfigItem, and since there is a parameter called verify_block, which is Proc, so if this operation has side effects, then unexpected behaviours may occur. Am I right?

Also I think this is easy to fix / avoid, just keey the array from available_options in parse and use it to create and everything will be fine.
