Error when clicking on a button inside a Pane that unmount the Splitpanes

[clemvnt]

Hello,

I get an error when I click on a button that is in a Pane that "unmounts" the Splitpanes.

The error is the following :

Uncaught TypeError: Cannot read properties of undefined (reading 'index')
    at W (splitpanes.js?v=d160eae9:88:27)
    at createElementBlock.onClick.P.<computed>.P.<computed> (splitpanes.js?v=d160eae9:277:47)
    at callWithErrorHandling (chunk-U3LI7FBV.js?v=59bb505e:2263:19)
    at callWithAsyncErrorHandling (chunk-U3LI7FBV.js?v=59bb505e:2270:17)
    at HTMLDivElement.invoker (chunk-U3LI7FBV.js?v=59bb505e:11202:5)

Reproduction project: https://stackblitz.com/edit/vitejs-vite-lm7mxadg
Splitpanes version : 3.0.1

+1 for this. I have a "close" button inside a pane that removes it, and I need to add a stopPropagation in order to prevent the error. However, that sometimes causes problems if there are other propagations that I do want to occur.

Edit: I believe I'm also running into this same error when I have a RouterLink inside a pane that changes the route

Any update on this?

The "splitpanes": "^4.0.4" version also has the same issue
