Keymaps that start with <space> cause delayed input in vim mode

[Philogy]

Summary

When I set a keymap that binds space i h it causes delays in other actions that end in space such as df<space>.

Description

When binding things to space Zed seems to incorrectly interpret certain commands as a clash with it so it introduces the input delay e.g. with the settings from the below example if you enter df<space>ih it'll ignore the df and just trigger editor::ToggleInlayHints this is unlike the default behavior in vim which would be to recognize df<space> as a complete command, execute it and then continue ih.

Steps to reproduce:

1. settings.json with { "vim_mode": true }
2. keymaps.json with:

  {
    "context": "Editor",
    "bindings": {
      "space i h": "editor::ToggleInlayHints"
    }
  }

3. Enter hello zed into a file
4. Go to beginning of line with <Esc>0
5. Enter df<space>, observe a delay before the hello is deleted
6. Comment out the binding, repeat 3-5
7. Observe no delay

Expected Behavior: The command is processed with no delay even when the key is mapped. Actual Behavior: There is an observable delay

I use space-as-leader bindings a lot, but I use a more constrained context. EG:

{
  "context": "Editor && !menu && VimControl && vim_mode == normal",
  "bindings": {
    "space *": "workspace::NewSearch",
    "space b": "tab_switcher::ToggleAll"
}

If I use your exact binding, then ya - df<space> has a delay. If you instead modify it to constrain the context properly, there is no delay.

@bd-rulch that makes sense, thanks! Any docs on this? The basic contexts Editor, Workspace make sense to me but I had trouble finding more information about menu, vim_mode & VimControl in the zed docs

@Philogy I found these things through looking at the contents of the vim keymap (vim: open default keymap from the command palette) but it looks like it's all documented here. Looking at that, the context for my bindings can be simplified a bit - I hadn't looked into what VimControl actually mapped to.
