search in Firefox causing unresponsive script window popup

[HarryF514]

Here is the full message from the pop up window:

A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue.

Script: http://localhost:9000/bower_components/jquery/dist/jquery.js:406

there are around 427 nodes in the tree structure. It mostly happened when we do a second search.

here is code I wrote:

scope.$watch('searchTerm', function(newValue, oldValue) {
                if (newValue !== oldValue) {
                    $scope.$broadcast('toggle-loader', true);
                    var searchTerm = newValue.trim();
                    if (searchTerm.length) { 
                        $scope.subgroupTree.treeInstance.jstree(true).search(searchTerm);
                    } else {
                        $scope.subgroupTree.treeInstance.jstree(true).clear_search();
                    }
                }

            });
