Original Pull Request: https://github.com/microsoft/terminal/pull/17794

State: closed
Merged: Yes

  1. Don't crash on a cmdpal "duplicate pane" of a snippets pane
    • Found while trying to solve bug the third.
    • "Duplicate pane" with a snippets pane would crash. This was due to us attempting to PreviewText when there was no buffer yet. (_activeBuffer() strikes again)
  2. dismiss the preview from cmdpal correctly too
    • Again while looking for part the third, I hit this
    • I have a sendInput(input: "a") command. This is the first command in the palette. And opening a new pane would... preview that command in the new pane? weird. Moving the line in CommandPalette::_close fixes this
  3. Don't crash when we're restoring a snippets pane and there's a bunch of windows

Don't crash when we're restoring a snippets pane and there's a bunch of windows * This was the real bug I was trying to fix * Looks like if you have enough panes & windows, there's enough of a delay between ctoring a snippets pane and actually calling `_UpdateSettings` on it, that the XAML loads and tries to bind to `_allTasks`, which _hadn't been constructed yet_ * closes #17793
