Deleting master window in tall layout changes width of (new) main window

[BombchuLink]

What did you expect to happen?

I expected the new master window, upon deletion, to take the exact same amount of screen space as the deleted one.

What actually happened?

The new master window, upon deletion, takes a lot less width than the deleted window.

Describe your attempts to resolve the issue

I tried refreshing the layout by using reload
I tried setting to a different layout and back to tall
I tried using once and setting the layout to tall

Steps to reproduce

1. start bsp-layout as tall
2. make windows
3. delete main window
4. see new main window size be very thin instead of the expected width :(
