Why do I get a [b in my filter after an action has executed?

[chipbite]

Hello! I am looking at https://thevaluable.dev/fzf-git-integration/ and wanted to be able to add values (git hashes) from the list in a file. For instance, for cherry picking later, or other things.

The setup works, but it has one problem.

Every time I execute the action (in this case bound to ctrl-s), it completes but next arrow down press enters some escape character (maybe?) in the filter, (and I believe my position in the list is reset due to this, as well).

So, I:

• Run the script,
• press ctrl-s to execute the second action, it completes as expected. I then
• press down arrow to continue along the list, but instead:
• The [b characters appear in the filter, and it filters the list...

Any ideas as to what this can be about?

Running in git-bash on windows terminal (sometimes mintty), which for the most part works pretty ok.

The script

Super simple adaptation of what is at https://thevaluable.dev/fzf-git-integration/.

Attempts:

• Tried both :execute: and :execute( ... )
• Tried both sh .c "<action>" and just the action without the shell start.

None made any difference.
