Did Android Gmail 4.2.1 break html intents? [close

Question

I've been using Intents to send HTML formatted emails using Gmail on Android from other apps. Today they stopped working. They look good in the Gmail compose display but all of the HTML tags get stripped when Gmail sends the email.

I've tried every variation of Intent formatting that I've seen posted and all HTML is stripped away. The result is always a multipart/alternative with a plain text and an HTML section containing an HTML-ized version of the plain text.

Is anyone else seeing this?

Any ideas for a work-around?
