Https://stackblitz.com/edit/angular-32h29m’s version 7 works by adding a drawable span tag to the outermost span tag, and I tried that it had to be a span tag

现在新版有解决办法吗

@simplejason I want to open a PR that does the following:

1. The indicator will always show by default
2. Add a new input to hide the indicator

WDYT?
