Problem

When Autocomplete elements are removed and re-added to the DOM (e.g., with Turbo navigation), a race condition causes
"Tom Select already initialized on this element" error.

Root Cause

disconnect() destroys TomSelect but leaves this.tomSelect pointing to the destroyed instance. If urlValueChanged()
fires before connect() (during re-attachment), it calls resetTomSelect() on the stale reference, triggering
double-initialization.

Impact

• Affects: Users with Turbo navigation, especially on mobile (Safari iOS)
• Symptoms: "Tom Select already initialized" console errors during navigation
• Fix: Single line addition prevents the race condition
• Risk: None - only affects the disconnect cleanup path

@Kocal I took the chance to add playwright tests. I'll submit another PR with some changes to the documentation to enhance the DX.

Thanks Marcus, that's much appreciated!

I only have some comments about the E2E test, and of course any documentation improvement is welcomed :)

• removed the browser test because I couldn't find a way to reproduce it here
• added a simple non-ajax example for Autocomplete

Ok, this is weird. I have force-pushed my changes this morning and the PR is still not updated. My changes are still being processed. 🤨

Rebased against 2.x and force-pushed again. Works now.

@Kocal After several attempts trying to reproduce the behaviour locally, I was unable to provoce it. How shall we move forward?
