Accessibility is using one of two methods to spell check text:

checkTextOfParagraph(*checker, text, TextCheckingType::Spelling, results, node->document().frame()->selection().selection());

or

node->document().editor().textChecker()->checkSpellingOfString(...)

and both require hitting the main thread, which goes against the goal of ITM.
