Autocomplete menu of `builtin.diagnostics()` still hangs there after closing telescope

Description

In builin.diagnostics() picker, press <C-l> to open the autocomplete menu for filtering the results by diagnostic type, however, without selecting any type, I press <C-c> to close telescope, this autocomplete menu will be hanging there forever.

UPDATE: Just now I tested builtin.lsp_document_symbols() picker and it has the same issue. It seems that this issue exists on all pickers that support the autocomplete menu.

Neovim version

NVIM v0.7.0-dev+797-gb218d02c4
Build type: Release
LuaJIT 2.1.0-beta3
Compiled by rockyzhang@mbp2021

Operating system and version

macOS 12.1 (the latest)

checkhealth telescope

telescope: require("telescope.health").check()
========================================================================
## Checking for required plugins
  - OK: plenary installed.
  - OK: nvim-treesitter installed.

## Checking external dependencies
  - OK: rg: found ripgrep 13.0.0
  - OK: fd: found fd 8.3.1

## ===== Installed extensions =====

## Telescope Extension: `fzf`
  - INFO: No healthcheck provided

Steps to reproduce

In a buffer with some diagnostics:

open the builtin.diagnostics() picker
press <C-l>, the autocomplete menu will popup
don't select any entry, press <C-c> to close telescope

You can see that the autocomplete menu won't be closed.

Expected behavior

The autocomplete menu should be closed after the diagnostic picker is closed
