Unable to preventDefault on 'a' tag in Browser.application about browser HOT 2 OPEN

Another solution was suggested in a StackOverflow post.

The solution is to add another pattern to update which matches on empty external URL, where we simply do nothing instead of trying to load the URL as we normally would with other external URLs. In regards to the question's example the following updated update function should do the trick:

update msg model =
   case msg of
       UrlRequested (Browser.Internal _) ->
           ( model, Cmd.none )

       UrlRequested (Browser.External "") ->
           ( model, Cmd.none )

       UrlRequested (Browser.External url) ->
           ( model, Browser.Navigation.load url )

       UrlChanged _ ->
           ( model, Cmd.none )

from browser.

Thanks @michaeljones for raising this issue (Elm 0.19). I've just run into the same problem. Your target="_self" trick works well for the time being.
