Bug: fzf-lua click handler switches to normal mode

[ObserverOfTime]

Self Checks

• I'm using the latest lualine.
• I didn't find the issue in existing issues or PRs.

How to reproduce the problem

• nvim -u lualine-fzf-issue.lua lualine-fzf-issue.lua
• click on the filename

Expected behaviour

The fzf terminal should be in insert mode.

Actual behaviour

The fzf terminal enters insert mode but then switches to normal mode.

Minimal config to reproduce the issue

require('lazy').setup({
    root = '/tmp/lazy',
    lockfile = '/tmp/lazy-lock.json',
    spec = {
        {
            'ibhagwan/fzf-lua',
            cmd = {'FzfLua'},
            opts = {
                fzf_bin = 'sk'
            }
        },
        {
            'nvim-lualine/lualine.nvim',
            opts = {
                sections = {
                    lualine_c = {
                        {
                            'filename',
                            path = 1,
                            on_click = function()
                                require('fzf-lua').files()
                            end
                        }
                    }
                }
            }
        }
    }
})

Additional information

The fzf terminal stays in insert mode when calling the function directly.
