autocorrect attribute behavior differs on contenteditable

Phenomenon

The autocorrect attribute, which controls automatic text correction on mobile keyboards, behaves differently on contenteditable elements compared to standard input elements. The correction suggestions may interfere with editing.

Reproduction example

1. Create a contenteditable div with autocorrect="on" or autocorrect="off".
2. On an iOS device, focus the contenteditable.
3. Type text with intentional misspellings.
4. Observe autocorrect behavior and compare with standard inputs.

Observed behavior

• In Safari on iOS, autocorrect may not respect the attribute value on contenteditable.
• Autocorrect suggestions may appear even when autocorrect="off".
• Behavior may differ from standard input elements.

Expected behavior

• autocorrect should work identically on contenteditable and standard inputs.
• The attribute value should be respected.
• Autocorrect should not interfere with IME composition.
