wicket can crash in response to a terminal resize

Start by reproducing the crash in wicket's update pane while repeatedly resizing the terminal, then trace the render path through RunnerCore::handle_event, UpdatePane::draw, draw_status_view, Popup::render, and Fade::render. Use the tui Buffer::get or Paragraph bounds-check backtrace to identify the failing resize case; done means the same resize sequence no longer panics.

@rmustacc ran into this doing a mupdate on madrid (he's running a tiling window manager), and I can recreate it locally: start wicket, move to the update pane (unclear if it's specific to the update pane, but I've only reproduced it here), and then spam resize the terminal. It will eventually crash with a backtrace along the lines of:
