Double closing brace from PairedBraceMatcher

I have a plugin for a custom language that has constructs like the following:

workflow foo {

   # content here

}

I implemented a PairedBraceMatcher (WdlBraceMatcher) for the language but I'm seeing odd behavior specifically for braces: when I type an opening `{` I get a closing `}` automatically, which is great! Unfortunately when I then press `Enter`, I get a second closing brace inserted, which breaks the code structure. Eg:

workflow foo {

  # cursor ends up here.

}

}

I found the option to turn off `Insert pair '}'` in Preferences but this hasn't been needed in any other language and seems like a strange default behavior (eg I typically write in Scala and haven't seen this double-closing before, despite the same option being on for me the whole time).

Is there any way I can restructure the PairedBraceMatcher or override smart keys in the plugin to prevent this from happening by default? Thanks!
