dragging subpatch tab to new window automatically closes it

[Nadpher]

latest nightly 0.9.4 up to commit 98ae0f7

MacOs Tahoe 26.3

whenever a window other than the first created floating window exists it automatically closes itself. this happens to subpatch windows. Abstraction windows stay alive until closed, upon which the entire program crashes.

workaround:
new patches allow creation of floating windows, that then can be replaced by the subpatch in question:

I don't think your description covers the issue very well. I'd change the topic to: dragging subpatch tab to new window automatically closes it
Since that is what is happening.

I cannot reproduce your other issue about "Abstraction windows stay alive until closed, upon which the entire program crashes."
For me it displays the same issue: click on abstraction -> opens in new tab -> drag tab out to new window -> closes again.

The workaround for getting the abstraction tab over to a new window is the same: open a new tab -> drag to new window -> drag abstraction tab to new window
When I close the abstraction tab/window plugdata keeps running (on 26.4.1)

In both cases it's possible to drag these tabs back into the original plugdata window.

Latest nightly also has an option to open patches into a new window automatically, this shows the same closing behavior.
