[Bug]: The btree layout cant retain the width/height of the resized window.

[lgjint]

Before you make the issue, confirm that

• You are running the master build from GitHub actions
• You have read the FAQ and the usage instructions
• You have searched pull requests and issues and have found none similar to your issue
• This problem comes from a failure in the tiling system and not a missing feature

Describe the bug

After adding a new window in a btree tile, it will revert to a fixed height-width split either by meta+t or by dagging on the edge of the window to resize it.

To reproduce

1. Add two windows into a tile.
2. Resize one window's width by meta+t or by dagging on the edge of the window.
3. Add a new window into the tile.

Expected behavior

The btree layout should retain the width/height of the resized window.

I could not reproduce this issue. Make sure you are running the latest commit build of the script. Try increasing the "Callback delay" slider in the script settings to around halfway if the latest commit doesn't fix this issue. Note that this will delay application of the new tile sizing for around 100ms, which may result in a marginally laggier experience.

Solved, the bug only occurs when Callback delay is set to 0.

But it seems that this kind of retention the width/height will continue even after closing all the windows in a tile, is it better to restore the default split ratio?
