Technically, this should be handled by either drirc or a drirc.d addition, not the actual libraries, as it is a software compatibility issue that calls for an application override.

The stock drirc is chock full of existing application overrides, it just seems either you’re missing the default configuration, or this application hasn’t been included yet.
