nvim-tree open file in new split buffer

[haunt98]

Description

Behavior change. Before when I open a file, neovim open buffer normally, no split windows or anything. After today update, everytime I open file, each open new split buffer. Is there any config to disable new behavior?

NVIM v0.9.0
Build type: Release
LuaJIT 2.1.0-beta3

Operating system and version

macOS 13.3.1 (a)

nvim-tree version

89816ace70642e9d3db0dab3dc68918f8979ec31

Steps to reproduce

1. nvim
2. open nvim-tree.lua
3. open file

Expected behavior

Open buffer normally, no split windows or anything.

Actual behavior

Everytime I open file, each open new split buffer.

This isn't minimal configuration at all. Please try with minimal configuration (no other plugins).

@gegoune Looks like my float config is mess up. After delete it went back normal. Thank you.
