Paste multiple line text sometimes corrupted in Cygwin bash shell

### Windows Terminal version

1.11.2921.0

### Windows build number

10.0.19042.1466

### Other Software

GNU bash, version 4.4.12(3)-release (x86_64-unknown-cygwin)

### Steps to reproduce

Add a profile for Cygwin.
```
{
"commandline": "C:\\cygwin64\\bin\\bash.exe -l",
"guid": "{09ff2493-xxxx-4ee9-xxxx-d7f90bb2xxxx}",
"hidden": false,
"icon": "C:\\cygwin64\\Cygwin-Terminal.ico",
"name": "Cygwin"
},
```

Open Cygwin bash shell in a Terminal tab window and execute `vi /tmp/temp.txt` and then paste multiple line text. For example:

### Expected Behavior

The text pasted in Cygwin bash shell as is.

### Actual Behavior

The text pasted in Cygwin bash shell corrupted sometimes. There is no such issue when using mintty.

No source file or test is named. Start by reproducing the issue with the provided Cygwin profile, GNU bash, vi, and the 40-line sample, then compare the behavior with mintty. Done means multiline text pastes into the Cygwin bash shell unchanged and the regression is covered by a suitable test.
