In my component's props TS interface, I can use JSDoc comments to set the description, and can even use the @default tag to describe the default value 💯
However, nothing happens when I use the @deprecated tag.

Some ideas:

• It would be nice i

IconButton does not 'blur' when it loses focus, retaining it's --background-focused class after the mouse or touch leaves the item.

I have an podcast with episode uploaded to Mixcloud. I also have my music uploaded to Soundcloud. I'd like to see Mixcloud and Soundcloud added as providers with Vime.js

Also I endorse the feature request for playlist.

I plan to use this with an Svelte app.

There are some basic accessibility issues on the landing page of Blaze which can be seen on Lighthouse.

Describe the bug
If you run the development server (yarn web dev), and run the Cypress tests,
(yarn web cy:run), you'll see that there are several console warnings.

To Reproduce
Steps to reproduce the behavior:

VSCode's syntax highlight is done by Textmate grammar. Basically it's defining some regex pattern to tokenize the code. And we could include other languages' rules as long as vscode knows how to deal with the included language.
