Had to make various other changes due to incompatibilities.
- Use the new `lit` package instead of `lit-html` or `lit-element`
- Drop `haunted` since it breaks the rules by specifying `type: module`
but then doesn't import with file extensions
- Use Sass Dart instead of node-sass (fixes#2445)
- Upgrade Karma
- Update to the latest @converse/skeletor (which uses mergebounce to batch writes)
- Flush storage before logging out
- Flush when reloading the tab
- Create initStorage method
when creating occupant from affiliation change stanza.
This means that when a presence for that occupant arrives, a duplicate
occupant is created (presumably because the original can't be find due
to the wrong nick being set).
Update storing of app settings. Store settings in a closured
`app_settings` object inside `@converse/headless/shared/settings`
Remove the `_converse.settings` object.
Url parameters mean that we don't get a match even when the URLs
actually match.
Could potentially use URI.js but gets cumbersome and since we restrict
to metadata coming from the MUC service (which we trust) I think it's OK
to remove it.
Fix minimizing by listening to change event
Fixes around showing/hiding and minimizing/maximizing
Don't trigger a `show` event on the model to show a chat, instead rely
on the `hidden` attribute which causes a rerender and will show/hide
chats.
In some cases a race condition can occur where a new message is received
before the MAM query starts.
Previously, the newly received message would be considered the latest
message to query from, thereby causing a gap in the history.
Looking at the Prosody code, it appears to be cheap since
Prosody will do nothing if you're already registered and this works
around a bug in mod_muc_rai where events aren't fired for each resource
of the same joined nick joining or leaving the MUC.
