Rete js crashes on Safari when a scrollable container is present

[k4v1cs]

Describe the bug

When there is a textarea with larger content present, so it has a scrollbar, the performance of Rete js greatly suffers, the app becomes unresponsive and in some cases crashes with out of memory error.

Example: https://codesandbox.io/p/sandbox/rete-js-v2-performance-forked-6w67jt
Recording of the issue (with lambdatest): https://github.com/user-attachments/assets/f572f5a3-263e-4e0e-ae7f-7f5cad4dffe5
The issue was also observed on a physical device.

Example to reproduce

https://codesandbox.io/p/sandbox/rete-js-v2-performance-forked-6w67jt

How to reproduce

• Have a larger number of nodes loaded in the editor
• Have a container displayed with scrollable content

In Safari the performance becomes vary bad, other browsers are not affected on the same device.

Expected behavior

• The performance should be the same as without the scrollable container

Thanks for reporting, I'll try to debug it asap

I've tested on the example with updated dependencies: https://codesandbox.io/p/sandbox/rete-js-v2-performance-forked-l4vwyx?workspaceId=53c9a236-3c26-40f8-8bba-91065c593869

Here's what I found while debugging:

• the page crashes regardless of the initialization of the editor: sometimes during the initialization of the editor, sometimes a few seconds after it has been initialized
• the crash does not happen with a textarea with long text doesn't have scroll (overflow: 'hidden' or large height)
• no crashes when textarea is added using JS (second button), not rendered by React.js https://l4vwyx.csb.app/#notextarea

I assume that Safari can't handle a large number of event listeners under certain circumstances, but it's not clear why (Safari's devtools don't give any clues)

Chrome DevTools does not show any anomalies. 90k event listeners is a lot, but not critical
