Alert cause security warning

Hello,

Each time i’m displaying an alert on my app got a :

WARNING: sanitizing HTML stripped some content

It’s not causing me any problems with my Alerts, but i would want to know how I can make this warning disapear.
I already got somme warning like that with urls and had to put a sanitizer.bypassSecurityTrustResourceUrl on them, but I don’t know how to do this with Alerts.

Thanks :slight_smile:
