Hydra mode with DAP?

[Kurren123]

I set up the following key maps for DAP:

    { "<leader>d", function() require("which-key").show({ keys = "<leader>_d", loop = true}) end, desc = "Debug" },
    { "<leader>_db", function() require("dap").toggle_breakpoint() end, desc = "Toggle Breakpoint" },
    { "<leader>_dj", function() require("dap").step_over() end, desc = "Step Over" },
    -- other dap keymaps, all starting with _d

The problem is when I start debugging and I have the <leader>d popup open in hydra mode. If I hit j to step over, the <leader>_d pop up opens again due to the loop = true. However sometimes it takes a second for a line of code to execute, so the neovim UI doesn't show that we're on the next line of code until I actually close which-key with <esc>.

In other words: Is there a way to do hydra mode without blocking neovim ui?
