This commit adds a menu item to the message context menu to
copy links that may exist inside of a message.
There are three possible scenarios:
1. There's no link in the message, which causes the menu to not
render the dedicated menu item at all
2. There's one link in the message, which renders an additional
`Action` with a copy-to-clipboard functionality
3. There are multiple links in a single message. This adds a
nested `PopupMenu` in the existing menu with menu items for each
link extracted from the message
To make this work there were some changes in the `PopupMenu` component
needed, as it wasn't take the sub menu's `enabled` state into account
properly. This makde it always render nested menus even when they
should've been invisible.
Closes: #1733
This is needed when accessing the context menu from the timeline status updates.
Previously, it'd only change the active channel because it assumed the user is already
in the chat view. This is no longer the case when in timeline view, so we need to make sure
we first navigate to the chat view.
This component introduces `StatusLetterIdenticon`, `StatusImageIdenticon`
and `StatusIdenticon`.
- `StatusLetterIdenticon` renders an identicon with a single letter based on a
name.
- `StatusImageIdenticon` renders an actual image based on an identicon URL
- `StatusIdenticon` is a composition of the former both, but with a loading mechanism
to decide which should be rendered
The commit also ensures all of these components are used respectively throughout
the application.
