use_ime=true conflicts with key assigments that defined in LEADER mode

[tizee]

What Operating System(s) are you seeing this problem on?

macOS

WezTerm version

wezterm 20211213-091602-1f958fa1

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

When use_ime=false, everything works fine.
When use_ime=true, key assigments with LEADER are swallowed and all of them fail to work.

To Reproduce

set use_ime=true in your configuration.

Configuration

local wezterm = require 'wezterm';

-- The filled in variant of the < symbol
local SOLID_LEFT_ARROW = utf8.char(0xe0b2)

-- The filled in variant of the > symbol
local SOLID_RIGHT_ARROW = utf8.char(0xe0b0)

wezterm.on("format-tab-title", function(tab, tabs, panes, config, hover, max_width)
  local edge_background = "#0b0022"
  local background = "#1b1032"
  local foreground = "#808080"

  if tab.is_active then
    background = "#2b2042"
    foreground = "#c0c0c0"
  elseif hover then
    background = "#3b3052"
    foreground = "#909090"
  end

  local edge_foreground = background

  -- ensure that the titles fit in the available space,
  -- and that we have room for the edges
  local title = wezterm.truncate_right(tab.active_pane.title, max_width-2)

  return {
    {Background={Color=edge_background}},
    {Foreground={Color=edge_foreground}},
    {Text=SOLID_LEFT_ARROW},
    {Background={Color=background}},
    {Foreground={Color=foreground}},
    {Text=(tab.tab_index+1) .. ":" .. title},
    {Background={Color=edge_background}},
    {Foreground={Color=edge_foreground}},
    {Text=SOLID_RIGHT_ARROW},
  }
end)

Expected Behavior

When use_ime=true, shortcut defined with LEADER modifier works.

Anything else?

I have to address this by modifying the code on handling KeyCode::Compose(String).
