Can anyone explain why these bullets will change color correctly in Firefox and IE, but not in Chrome (my current version is 47.0.2526.106)? Why do the bullets in the first ul stay white, but the others change initially?
Note that I get the same behavior whether I bind to class or use the ng-class attribute.
Is there any way to get the colors to update correctly?
Firefox/IE:
Chrome:
angular.module('myApp', [])
.controller('myCtrl', [
'$scope',
'$interval',
function($scope, $interval) {
var values = ['Hello', 'Oops', 'Uh-Oh...'];
var classes = ['good', 'warning', 'danger'];
var nItems = 8;
$scope.items = [];
for (var i = 0; i < nItems; i++) {
$scope.items.push({});
}
function updateItems() {
for (var i = 0; i < $scope.items.length; i++) {
var item = $scope.items[i];
var chosen = Math.floor(Math.random() * values.length);
item.value = values[chosen];
item.class = classes[chosen];
}
}
$interval(updateItems, 3000);

Coming back to this about a year later it appears Google has fixed the rendering bug that caused this, although I'm not sure exactly which release included the fix. I no longer see this issue on Chrome v56.0.2924.87.

- Clearly the root cause is the $interval statement. Calling it with $timeout and at the end of the updateItems calling it again with another $timeout produces the same interval effect, but get the correct display. Not sure why. I'd love to hear the technicals behind this. – Will Commented Dec 28, 2015 at 22:33

Reset to default 6This is a Chrome rendering bug.
One option is to insert custom bullet points using a pseudo element.
ul {
display: inline-block;
list-style: none;
}
ul li:before {
content: '\2022';
text-indent: -1em;
display: inline-block;
}
Here is the updated example:
angular.module('myApp', [])
.controller('myCtrl', [
'$scope',
'$interval',
function($scope, $interval) {
var values = ['Hello', 'Oops', 'Uh-Oh...'];
var classes = ['good', 'warning', 'danger'];
var nItems = 8;
$scope.items = [];
for (var i = 0; i < nItems; i++) {
$scope.items.push({});
}
function updateItems() {
for (var i = 0; i < $scope.items.length; i++) {
var item = $scope.items[i];
var chosen = Math.floor(Math.random() * values.length);
item.value = values[chosen];
item.class = classes[chosen];
}
}
$scope.getItemValue = function(item) {
return item.value;
};
$interval(updateItems, 3000);
}
