I've encountered the same issue. Confirmed that the pattern and auto-validation works on similar paper-input element but not on the paper-textarea one. The docs for paper-textarea claim that this functionality is available though:

Any update on this issue. I'm also facing similar issue in my project.

I've been able to reproduce this behaviour as well. Until the issue is fixed, could you please remove pattern property from paper-textarea docs?
