Also make uses of `performFunctionOnMainThread` typed with `AccessibilityObject*` instead of `AXCoreObject*`.

"make uses" -> "make use" or "uses".

--- a/Source/WebCore/accessibility/AccessibilityObject.h
+++ b/Source/WebCore/accessibility/AccessibilityObject.h

-    String computedLabel() override;
+    WEBCORE_EXPORT String computedLabel();

Why it needs WEBCORE_EXPORT, it didn't before in AXCoreObject.

-    LayoutRect boundingBoxRect() const override { return LayoutRect(); }
+    virtual LayoutRect boundingBoxRect() const { return LayoutRect(); }

return { };

--- a/Source/WebCore/accessibility/isolatedtree/AXIsolatedObject.cpp
+++ b/Source/WebCore/accessibility/isolatedtree/AXIsolatedObject.cpp

-    performFunctionOnMainThread([&value](AXCoreObject* object) {
+    performFunctionOnMainThread([&value](AccessibilityObject* object) {

Missing space between ](

 void AXIsolatedObject::setSelected(bool value)
 {
-    performFunctionOnMainThread([&value](AXCoreObject* object) {
+    performFunctionOnMainThread([&value](AccessibilityObject* object) {

Dito.

 void AXIsolatedObject::setSelectedRows(AccessibilityChildrenVector& value)
 {
-    performFunctionOnMainThread([&value](AXCoreObject* object) {
+    performFunctionOnMainThread([&value](AccessibilityObject* object) {

Dito.

 void AXIsolatedObject::setFocused(bool value)
 {
-    performFunctionOnMainThread([&value](AXCoreObject* object) {
+    performFunctionOnMainThread([&value](AccessibilityObject* object) {

Dito.
 void AXIsolatedObject::setSelectedText(const String& value)
 {
-    performFunctionOnMainThread([&value](AXCoreObject* object) {
+    performFunctionOnMainThread([&value](AccessibilityObject* object) {

Dito.

 void AXIsolatedObject::setSelectedTextRange(const PlainTextRange& value)
 {
-    performFunctionOnMainThread([&value](AXCoreObject* object) {
+    performFunctionOnMainThread([&value](AccessibilityObject* object) {

Dito.

 void AXIsolatedObject::increment()
 {
-    performFunctionOnMainThread([](AXCoreObject* axObject) {
+    performFunctionOnMainThread([](AccessibilityObject* axObject) {

Dito.

 void AXIsolatedObject::decrement()
 {
-    performFunctionOnMainThread([](AXCoreObject* axObject) {
+    performFunctionOnMainThread([](AccessibilityObject* axObject) {

Dito.

I'm not entirely sure. Before my patch the function was virtual, which may have implicitly exposed it. Without WEBCORE_EXPORT, we fail to link because WebProcess/Automation/WebAutomationSessionProxy.cpp calls `computedLabel()`.
