Failed to create input element: {e:?}

Error message

Failed to create input element: {e:?}

What it means

In gpui_web window construction: creating the hidden DOM input element used for text input failed (document.createElement errored). This is a browser DOM failure during window initialization — the web text-input bridge cannot be set up.

Solutions

1. Verify the DOM environment allows dynamic element creation (CSP, sandbox flags)
2. Create the input element once and reuse it across window rebuilds
3. Surface the JS error detail when text-input setup fails so the page environment issue is diagnosable
