setTemporaryUnderline in CodeEditorComponent on macOS

Hi all, just came across this (usually develop on windows but decided I’d had enough of vs for the day), essentially entering any text into my CodeEditorComponent hits

void CodeEditorComponent::setTemporaryUnderlining (const Array<Range<int> >&)
    jassertfalse; // TODO Windows IME not yet supported for this comp..

not sure if I’m doing something wrong or if this is a known bug, don’t think I’m trying to add any non ascii characters (as mentioned in Can't input any non-ascii chars in CodeEditorComponent), and I can get around it by overriding the setTemporaryUnderlining function in my subclassed CodeEditorComponent, but thought I’d throw it out there!
