The overflow was set to "hidden". I'm unsure of how this was even
working on desktop, but the #user-presences div certainly would
not scroll on mobile. This enables mobile scrolling.
For bots and users who have not logged in for a long time the presence information is not known. For the these users make the presence indicator hidden.
Before this commit, hovering over the blank area of a stream
would not reflect its "clickability". This behavior is
inconsistent with other clickable lists, such as the user sidebar.
This commit changes the cursor to a pointer when hovering over a
stream and removes annoying pointer-default-pointer changes when
hovering with the mouse over multiple users in the user sidebar.
This changes the right sidebar unread count styling to match the left
sidebar styling — in that they all now should have a 4px border radius
on the edges of the unread count blocks.
Transfer css from right-sidebar.css to components.css to make it reusable.
The 'margin-bottom' property is removed from 'input-append' class as
it does not affect the styling of the element.
A clear-search option to clear the user-list searchbox has been added.
This feature was present in the main searchbar but absent elsewhere.
Fix a part of #3716.
