I have a problem that might interest some. I was using sweet alert 2 in my lightning component bundle "pages". It was working like a charm:



But now, in my sandbox after the summer 18 update the sweet alert modal turned into a bitter corner alert:



Can anyone please help me? I uploaded the js file from the sweet alert website as a static resource in SalesForce.
I am not sure if the css from sweet alert is being modified by the theme or if it is something else, but I don't know how to fix it, and I have to until this update is applied to production orgs. I also accept suggestions of modals, but I did not find anything as easy and nice looking as this.
