window hint breaks popup windows from other plugins

[sufftea]

The problem

After opening and closing hydra's window hint, the windows of other plugins stop closing properly. For example, when I open a vim.lsp.buf.hover window, it doesn't disappear after I move the cursor. The same happens to neo-tree's floating window.

Update: noticed another bug that probably has the same root: when I yank something, the selection doesn't blink.

All of this starts happening only after hydra shows its window hint.

Steps to reproduce

1. Use the config
2. Press <leader>dh to start hydra
3. Press <Esc> to close it
4. Open a vim.lsp.buf.hover window, or neo-tree's floating window.
5. Try to close that window
6. It doesn't close

Config

      local dap = require("dap")
      local hint = [[

        ----^-^-^-^--^-^----  ^-^-------------------
            ^ ^back^ ^ ^     ^_b_: toggle breakpoint
            ^ ^ _C_^ ^        _B_: clear breakpoints
        out _H_ ^ ^ _N_ into  _g_: continue
            ^ ^ _T_ ^ ^       _x_: terminate
            ^ ^over ^ ^     ^^_r_: open repl

            ^ ^  _<Esc>_: exit
       ]]
      require("hydra")({
        name = "Debug",
        hint = hint,
        config = {
          color = "pink",
          invoke_on_body = true,
          hint = {
            type = "window",
            border = "rounded",
          },
        },
        mode = { "n" },
        body = "<leader>dh",
        heads = {
          { "H", dap.step_out, { private = true, desc = "step out" } },
          { "T", dap.step_over, { private = true, desc = "step over" } },
          { "C", dap.step_back, { private = true, desc = "step back" } },
          { "N", dap.step_into, { private = true, desc = "step into" } },
          { private = true, "b", dap.toggle_breakpoint, { private = true, desc = "toggle breakpoint" } },
          { "B", dap.clear_breakpoints, { private = true, desc = "clear breakpoints" } },
          { "g", dap.continue, { private = true, desc = "continue" } },
          { "x", dap.terminate, { private = true, desc = "terminate" } },
          { "r", dap.repl.open, { private = true, exit = true, desc = "open repl" } },
          { "<Esc>", nil, { private = true, exit = true, nowait = true, desc = "exit" } },
        },
      })

A temporary solution for me was to change hint.type to statusline*, and write my own logic for showing the hint window inside on_enter and on_exit.

*there seems to be another bug that statusline doesn't show up on pink hydras, but that's another story.
