The Peek Definition window is not aligned to left side when opened in a left side window of a split.

Describe the bug

Repro Steps:

1. Split the neovim window vertically.
2. Call Peek Definition command on any symbol on the left split window.
3. The Peek Definition window is not aligned to left side when opened in a left side window of a split.

• When opening with no split or opening on the right side of a split the preview definition window aligns to the full size of the screen or the split.

These are my settings:

lspsaga.setup({
  ui = {
    border = "single",
    devicon = true,
    title = true,
  },
  lightbulb = {
    enable = false,
    enable_in_insert = true,
    sign = true,
    sign_priority = 40,
    virtual_text = true,
  },
  symbol_in_winbar = {
    enable = false,
    separator = " ",
    ignore_patterns={},
    hide_keyword = true,
    show_file = true,
    folder_level = 2,
    respect_root = false,
    color_mode = true,
  },
  definition = {
    width = 0.99,
    height = 0.4,
  },
})

Steps to reproduce

use min.lua https://github.com/nvimdev/lspsaga.nvim/blob/main/test/minimal_test.lua for test
nvim --clean -u min.lua example.lua

Repro Steps:

1. Split the neovim window vertically.
2. Call Peek Definition command on any symbol on the left split window.
3. The Peek Definition window is not aligned to left side when opened in a left side window of a split.

I've reproduced this in a lua file and a c and cpp file types.

Expected behavior

The Preview Definition window should open up and align to the left side of the screen on a vertical split.

Neovim version (nvim -v)

0.9.5

Terminal name/version

Neovide, Windows Terminal

Start with test/minimal_test.lua and reproduce the issue using nvim --clean -u min.lua example.lua. Then trace the Peek Definition window positioning for a vertically split Neovim window, especially when the current split is on the left. Done means the preview aligns with the left side of its split in the reported cases without changing the existing full-screen or right-split behavior.
