Keymap editor does not delete or override defaults correctly

[unikitty37]

Reproduction steps

1. Open the keymap editor.
2. Click the Search by Keystroke button and press ⌥⌘T.
3. You should see that "agent: new thread" and "pane: close other items" have this keystroke.
4. Right-click on the "agent: new thread" line and choose Delete.
5. Double-click on the "pane: close other items" line, click in Edit Keystroke, and press ⇧⌃⌘T.
6. Click Save.
7. Close and reopen the keymap editor, and search for ⌥⌘T.
8. Search for "editor: wrap selections in tag" and try to assign it to ⌥⌘T.

Current vs. Expected behavior

Expected behaviour:

At the end of step 6, the keymap editor should be showing two entries:

• "agent: new thread" with no keystroke next to it.
• "pane: close other items" with ⇧⌃⌘T next to it.

At the end of step 7, there should be no matches.

Step 8 should not produce any warnings about clashing keystrokes, because the previous steps deleted one clashing binding and changed the other.

(Aside: ⌥⌘T should already be the default for "editor: wrap selections in tag" when using the TextMate base_keymap, because that is what it's bound to in TextMate…)

Actual behaviour

At the end of step 6, there are three entries:

• <null> with ⌥⌘T (and the same context as the agent: new thread line, but with a source of "User").
• agent: new thread with ⌥⌘T next to it, but it is now greyed out.
• pane: close other items with ⌥⌘T next to it.

After step 7, the same results are achieved.

Step 8 produces a warning that there are 3 clashing bindings, when there were only 2 at the start of this.

The following entries have been added to keymap.json:

  {
    "context": "(AgentPanel && acp_thread)",
    "bindings": {
      "alt-cmd-t": null
    }
  },
  {
    "context": "Pane",
    "bindings": {
      "ctrl-cmd-shift-t": [
        "pane::CloseOtherItems",
        {
          "close_pinned": false
        }
      ]
    }
  }

Sadly, this all appears to be Rust-related noise from another window and nothing much about the keymap editor :(

Hey @unikitty37 I tried to follow your steps, but ran into an issue of my own: my keybinding wasn’t updated in the UI after step 5, even though I expected it to be. Then, when I tried to edit it again, I got this warning:

Stuff’s definitely wonky with the keymap editor. Thanks for the report!

[yeskunall]

Ignore the incorrect keybinding in the screenshot, I ⌘⇥’d away to paste it.
