- Rather than have a `showing` prop on the fixed popover, I just remove it and put a span in it's place when it's gone. This means we always get componentDidMount when the popover appears and simplifies when to focus it's content.
- The fixed popover implements esc and blur behaviors itself
- The fixed popover uses the background-secondary color and works in dark mode
- The snooze items have hover and active states
Summary:
- Add FixedPopover, an absolutely positioned popover component to use for swipe snoozing:
- This component needs to be finished, as its current behavior is primarily for the snooze plugin
- Updates popover.cjsx to properly render pointer for thesnooze popover for the `down` direction
- Adds new design assets
- Adds date input to snooze popover
Test Plan: - TODO
