I found an extra focus event was also fired during NumberInputType::handleBlurEvent().

In the following stack trace, the deeper updateFromElement() is not needed.  We need to avoid it....

1   WebCore::HTMLTextFormControlElement::dispatchFocusEvent()
2   WebCore::Document::setFocusedNode(WTF::PassRefPtr<WebCore::Node>)
3   WebCore::FocusController::setFocusedNode(WebCore::Node*, WTF::PassRefPtr<WebCore::Frame>)
4   WebCore::SelectionController::setFocusedNodeIfNeeded()
5   WebCore::SelectionController::setSelection(WebCore::VisibleSelection const&, unsigned int, WebCore::SelectionController::CursorAlignOnScroll, WebCore::TextGranularity, WebCore::DirectionalityPolicy)
6   WebCore::SelectionController::textWillBeReplaced(WebCore::CharacterData*, unsigned int, unsigned int, unsigned int)
7   WebCore::CharacterData::setDataAndUpdate(WTF::PassRefPtr<WTF::StringImpl>, unsigned int, unsigned int, unsigned int)
8   WebCore::CharacterData::setData(WTF::String const&, int&)
9   WebCore::replaceChildrenWithText(WebCore::HTMLElement*, WTF::String const&, int&)
10  WebCore::HTMLElement::setInnerText(WTF::String const&, int&)
11  WebCore::RenderTextControl::setInnerTextValue(WTF::String const&)
12  WebCore::RenderTextControlSingleLine::updateFromElement()
13  WebCore::updateFromElementCallback(WebCore::Node*)
14  WebCore::ContainerNode::dispatchPostAttachCallbacks()
15  WebCore::ContainerNode::resumePostAttachCallbacks()
16  WebCore::Document::recalcStyle(WebCore::Node::StyleChange)
17  WebCore::Document::updateStyleIfNeeded()
18  WebCore::Document::updateLayout()
19  WebCore::SelectionController::textWillBeReplaced(WebCore::CharacterData*, unsigned int, unsigned int, unsigned int)
20  WebCore::CharacterData::setDataAndUpdate(WTF::PassRefPtr<WTF::StringImpl>, unsigned int, unsigned int, unsigned int)
21  WebCore::CharacterData::setData(WTF::String const&, int&)
22  WebCore::replaceChildrenWithText(WebCore::HTMLElement*, WTF::String const&, int&)
23  WebCore::HTMLElement::setInnerText(WTF::String const&, int&)
24  WebCore::RenderTextControl::setInnerTextValue(WTF::String const&)
25  WebCore::RenderTextControlSingleLine::updateFromElement()
26  WebCore::NumberInputType::handleBlurEvent()
27  WebCore::HTMLInputElement::handleBlurEvent()
28  WebCore::HTMLTextFormControlElement::dispatchBlurEvent()
29  WebCore::Document::setFocusedNode(WTF::PassRefPtr<WebCore::Node>)
30  WebCore::FocusController::advanceFocusInDocumentOrder(WebCore::FocusDirection, WebCore::KeyboardEvent*, bool)
31  WebCore::FocusController::advanceFocus(WebCore::FocusDirection, WebCore::KeyboardEvent*, bool)
