Strange behaviour with Neovim / Fugitive

[phantomwhale]

I have lefthook set up and running nicely from the command line. By default, we only have a pre-push hook; we do nothing for pre-commit.

If I git commit from the shell, I am taken into a neovim editor very quickly to type the message (no hooks to run!)

Lefthook is installed via brew on my MacOS

However, when I am in neovim, running the Fugitive plugin, if I run the :Git commit command, before it opens up the window to put in the commit message, it shows the following in the messages bar:

^[]11;?^[\^[[6n

In then also freezes for 3-4 seconds, as if something is running, before taking you to the commit message screen (or if you hit the enter key a few times, it seems to break the flow, and an empty window opens up instead?!)

I've tried to debug further, but I'm struggling to recreate this outside of neovim. I am aware of tpope/vim-fugitive#1446 but this feels slightly different, and perhaps more lefthook specific?
