Add pulse animation to selected element in PX

I recently saw an onboarding flow for a product I was using and their guided walkthroughs also provide a pulse animation on the element.

It would be great if PX could do the same.

I did take a look at using PX to add in CSS3 pulse animations but it doesn’t accept CSS3 in the editor unfortunately.

Current workaround is to add a badge icon or hotspot which isn’t ideal.

Note: @Brianna Goodrum posted a similar idea about guide animations but appears to be more related to the delivery of the guide (grey box in the example above) than of the element selected.
