Typed input is sometimes wrongly ordered

Windows Terminal version

1.20.11781.0

Windows build number

10.0.19045.3930

Other Software

Bash from Git for Windows

Steps to reproduce

I cannot tell exactly how to reproduce.
But it happens regularly.
The prompt is not ready yet because it still executes the last command or evaluates the PROMPT_COMMAND of Bash.
Then I already type the next command like git b -a (b here is a Git alias for branch -vv).

Now regularly it happens that once the prompt is ready what is inserted is misordered, like agit b -, so the characters typed later are input before characters typed earlier.

I first thought I just mistyped, but I'm absolutely sure now, that I did not mistype, but the characters were not inserted in the order I typed them.
I guess there is some race condition somewhere that causes this.

Expected Behavior

Input appears in the order I typed it.

Actual Behavior

Input is mixed up.

No source file, test, or entry point is identified. Begin by establishing a reliable reproduction involving Bash from Git for Windows, a still-running command or PROMPT_COMMAND, and typed input; done means input consistently appears in the order it was typed.
