This prevents it from being persisted across page loads and makes more
sense logically.
Also move markScrolled to utils and MUC unread messages indicator to bottom panel.
If set to a positive integer, the chat history will be kept to that size
by removing older messages.
This happens as new messages come in (as long as the chat isn't scrolled up)
and when the user scrolls down.
Also add the `pruning_behavior` setting
Instead of on the views/components.
We still have `close` methods on the components, but they are just
event handlers and not external API methods to be called by other code.
Instead `close` should be called on the model.
This is largely a leftover from the Backbone.View days and makes less
sense now that the UI is componentized.
Ideally we don't want to call commands on the "views themselves, instead
we should be working on the the models and let the "views" update
themselves automatically.
Also, given that the `jid` attribute on the chat views might change,
especially when rendered declaratively in other frameworks like React,
a view might not be available at times where we previously might have
expected it to be (since it's been repurposed for a different JID).
On the `<converse-chat-content>` element. This removes the need for all
the manual scrolling.
Firefox finally supports this feature. Unfortunately Firefox ESR doesn't
yet, but I can't wait anymore.
This wrongly stored value wasn't inlcuded in the published the bundle
because the libsignal store was used, which had the right value for the public key.
Instead, this value was used locally by being passed to the libsignal
session builder to verify signed prekey.
Previously they were of type ElementView from @converse/skeletor
The ElementView component is merely a helper to allow us to eventually
migrate everything to Lit
