[bug]: very slow in zsh(msys) on windows (not wsl)

[BlockLune]

Describe the bug

I'm using Zsh (based on the Git bash) on Windows and I'm using this plugin. In most cases it works fine. However, when it comes to switching git branches, it becomes super slow. You can see the recordings below. After pressing the m key on the keyboard, I waited about 100 milliseconds for it to show up on the screen, and it did so for every letter in the rest of ian after that. Using the backspace key to delete does the same thing.

Steps to reproduce

1. Follow this to install zsh in windows git bash
2. cd to a git repo and try to git checkout

Expected behavior

It should be as fast as when I type any other command.

On Cygwin, it is mostly fine. But when it comes to awk, then it got super slow, leading to delay in typing.

Simple to reproduce:

awk '{print hello}' 1.txt

The slowness will appear when typing within the {}, so print will be prnt under normal typing speed.
