Reviewed by Chris Fleizach.

When creating an AXIsolatedTree, we didn't sync the current frame selection into AXIsolatedTree::m_selectedTextMarkerRange,
meaning it would be wrong until it changed again. This commit syncs the frame selection when creating the tree, ensuring
m_selectedTextMarkerRange is right from the start.
