Notes

The partial support in mobile browsers results from their OS generally having built-in spell checking instead of using the wavy underline to indicate misspelled words. spellcheck="false" does not seem to have any effect in these browsers.

Browsers have different behavior in how they deal with spellchecking in combination with the the lang attribute. Generally spelling is based on the browser's language, not the language of the document.

Bugs

Browsers can behave differently on when they should check spelling (e.g. immediately or only on focus)
