Today

• Bridge is busted! Sorry about that.
• No episode next week due to travel, nor during the last week of November
• The ES6 Classes patch landing (yay!) we can now focus on the HTML-ification patch - there's review feedback to address.
• Review feedback on https://phabricator.services.mozilla.com/D326631
  • "Set type="icon ghost" on the button in DownloadsViewUI.sys.mjs, and keep only size and margin on ::part(button), dropping the color, border and hover/active variable overrides"
    • "I didn't verify that, but it would be a good idea to test Windows HCM and verify these claims, just to be sure we're not regressing it."
  • "content: url() is supported on XUL <image>, but the frame type is picked at construction and XUL images don't reframe when content changes. Could you check that the blocked subview's icon shows on first open (with Nova off)?"

```
