CJK Characters doesn't render correctly on Alacritty (v2_develop)

[xiongnemo]

Describe the bug
As title, but this works quite well in v1 on Alacritty

This is a continuation of #2928

To Reproduce
Steps to reproduce the behavior:

1. Use Alacritty
2. In the directory, dotnet run --project Examples/UICatalog/UICatalog.csproj (dotnet run --project UICatalog/UICatalog.csproj on v1)

Expected behavior
Runes should be rendered correctly

Screenshots
Alacritty, v2_develop and v2_release (renders incorrectly):

Windows Terminal, v2_develop and v2_release (seems normal):

Alacritty, v1_release (seems normal):

Windows Terminal, v1_release (renders incorrectly):

Additional context
As per microsoft/terminal#17016 and microsoft/terminal#16825 , I can't 100% sure whether this is a Terminal.Gui problem or the corresponding terminal emulator's.

Issue does not manifest with v2net driver (start UICatalog with -d v2net

It does manifest in v2win, implying there is indeed something funky going on.

v2 net (fine)

v2 win (bad)
