title: How can I inject custom line breaks on a symbol layer label?
body: <p>Is there a way to override the default "text-max-width" label wrapping and inject my own custom line breaks on a symbol feature label? Unfortunately for my current uses, "text-max-width" is strictly defined by em units and not actual character limits. </p>
  
  <p>I'm attempting to break at specific characters and was hoping that setting "text-max-width" to 0 would give me control over line breaks. Currently if I inject "\n" within my string while "text-max-width" = 0, those custom breaks will be ignored and the label will instead be drawn as a single line.</p>
  
  <p>Is there currently a way to work around this in mapbox-gl-js; or would this type of functionality be a new feature?</p>
