I can’t get the new Twitter timeline embedding feature to work.
Apparently anybody can embed anybody’s Twitter timeline now, providing said timeline is not “protected”, which is the default setting anyway. I tried different accounts, the @TwitterDev one, several, no luck: Only a text link. I built test pages, tried different browsers, and even different web server. I can’t imagine that the service itself could be broken for days like this, so I must be doing something wrong, I’m really asking for help here.
Logged on, in the “Settings and privacy” menu entry, there is a “Widgets” tab that gets you to a page that says “You currently have no widgets” with a “Create new” button next to it ; Clicking said button produces a menu where choosing “Profile” (is that how you create a timeline widget?) takes you to a page where you enter the name of the user whose timeline you want to embed.
There are examples, it’s really a simple wizard, you can seemingly embed anything, without any specific id.
Then, a message saying “That’s all we need, unless you’d like to set customization options ; By embedding Twitter content in your website or app, you are agreeing to the Developer Agreement and Developer Policy.” end of quote, emphasis mine ; and here is the code snippet :
Tweets by TwitterDev
Of course, I tried prefixing the URL with http or https, but I also know that the ssl-agnostic “//” prefix is the good practice, and of course that changed nothing 
Now at this stage, if you go back to you “widgets” settings tab, it still says “You currently have no widgets.” so, hum 
And here is what happens when I copy and paste the code snippet :

Only text links are displayed, the timeline is not rendered. The external JS script is pulled in OK though, I checked.
Am I missing something here? What is going on?
