Wezterm resize when covered by window after changing settings

[Gavin1937]

What Operating System(s) are you seeing this problem on?

Which Wayland compositor or X11 Window manager(s) are you using?

Mutter

WezTerm version

20240203-110809-5046fc22

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

stable version (20240203-110809-5046fc22)

While wezterm is completely cover/block by another program, we change its config and save several times to trigger a config reload. And then use Alt+Tab to switch back to wezterm window. Repeat this several times then wezterm window will resize itself after each Alt+Tab

nightly version (20240812-215703-30345b36)

I can't move wezterm window at all, so I can't reproduce the bug.

To Reproduce

1. open wezterm and another program (vscode in my case, I use it to edit my config)
2. use vscode to completely cover/block wezterm window
3. modify wezterm config, and save it to trigger wezterm hot reload
4. use Alt+Tab to switch wezterm window on top
5. pay attention to the bottom of wezterm window, it will shrink itself
6. if step 5 didn't happen, repeat step 3-5 several times

Configuration

-- Pull in the wezterm API
local wezterm = require 'wezterm'
local act = wezterm.action

-- This will hold the configuration.
local config = wezterm.config_builder()

-- This is where you actually apply your config choices

-- custom key bindings
config.keys = {
  -- selection copy mode
