On mobile devices, the combination of enterkeyhint and inputmode attributes may affect Enter key behavior inconsistently on contenteditable elements. The Enter key may insert line breaks when it should perform an action, or vice versa.
On iPhone/iPad Safari, when entering text or pressing "return" multiple times in a contenteditable element, the software keyboard appears but hides the text being typed. The page doesn't auto-scroll to keep text visible. Works fine on Android and other browsers.
When a page with a contenteditable element responds to media query changes (e.g., orientation change, window resize), the layout changes may disrupt editing. The caret position may jump, and selection may be lost.
The `inputmode` attribute, which should control the type of virtual keyboard shown on mobile devices, does not work on contenteditable regions in iOS Safari. The keyboard type cannot be controlled.
On iOS, contenteditable elements may become non-selectable or non-editable. Tapping on the element doesn't display the caret, preventing text input.
