It had ~32px of overflow causing a horizontal scrollbar. Turns out the layout engine gets confused when hidden elements are at the end of a flexbox, so we just move them higher in the DOM (where they logically still make sense).
The remaining changes are all alignment and misc changes in that respect, and probably not obvious.
The tag options are not implemented out of concern for diff size.
This splits the context menu classes out to a new "iconized" style which is common across a number of context menus, including the UserMenu.
Some of the badge/sublist styles had to change to better accommodate the menu icon lining up.
This also contains the framework required for https://github.com/vector-im/riot-web/issues/13961
The 'sort by' radio buttons are blocked by https://github.com/matrix-org/matrix-react-sdk/pull/4731 as it contains the styles needed.
The 'unread rooms' checkbox is intentionally not hooked up. This is a more complicated refactoring that needs to be done.
The message preview checkbox works, though the previews remain hardcoded in this change. The primary intent of this change is to have a good enough context menu and the hover states.
The hover states are as described in the design.
This is a work in progress, but covers the coarse areas. This uses all-new classes to better describe what everything is, and to reduce the number of selectors we keep track of.
This is primarily layout for the list and not actually the final structure. For example, some buttons are missing and other areas are not styled correctly - the idea in this commit was to get things roughly in the right place and work on it.
