Looks like get_viewport()->gui_get_focus_owner() is null after hitting escape, so it passed null to is_ancestor_of.

godot/editor/code_editor.cpp

Lines 773 to 778 in 31a7fd1

	if ((find_replace_bar != nullptr && find_replace_bar->is_visible()) && (find_replace_bar->has_focus() || find_replace_bar->is_ancestor_of(get_viewport()->gui_get_focus_owner()))) {
	if (ED_IS_SHORTCUT("script_text_editor/find_next", key_event)) {
	find_replace_bar->search_next();
	accept_event();
	return;
	}

@KoBeWi It's because the e21c30e made the search box ( which is a lineEdit ) lose focus when input is ui_cancel.

Any suggestion how to fix this? Maybe make it the default behaviour and add some null protection, or we make it a special case.
