OpenFileDialog crash on macOS 15.7.3

[jdotrjs]

Description

FileFilters make it possible to hard crash macos

To Reproduce

app.go

func (a *App) PickFile(title string, patterns string) (string, error) {
	homeDir, _ := os.UserHomeDir()
	opts := wruntime.OpenDialogOptions{
		Title:            title,
		DefaultDirectory: homeDir,
		Filters:          []wruntime.FileFilter{},
	}
	if patterns != "" {
		opts.Filters = []wruntime.FileFilter{{
			DisplayName: title,
			Pattern:     patterns,
		}}
	}
	return wruntime.OpenFileDialog(a.ctx, opts)
}

app.tsx

import './app.css';
import { h } from 'preact';
import { AppProvider } from './lib/AppContext';
import { PickFile } from './api/client';

export function App() {
  return (
    <AppProvider>
      <button class="btn" onClick={async () => { const p = await PickFile("test", ""); }}>
        Work
      </button>
      <button class="btn" onClick={async () => { const p = await PickFile("test", "busted;busted.exe"); }}>
        Crash
      </button>
    </AppProvider>
  );
}

Expected behaviour

File dialog should open for both buttons

Actual behavior

"Work" opens a file selection dialog

"Crash" ... does not:

Attempted Fixes

Non, mostly a bunch a variations on the FileFilter contents to see what triggers the crash. I think it's more than one entry, e.g., ; usage.
