My angularjs single page application is encountering issues specifically in IE9, despite functioning perfectly in Chrome and Firefox. The initial load involves downloading a substantial amount of data and managing numerous dependencies through requireJS.
Upon launching the webpage in a new IE session, certain elements fail to display on the screen as expected. Upon inspecting the network requests, it becomes apparent that some items are missing. Reloading the page resolves the issue since some files have already been cached; however, clearing the cache and retrying results in the same problem occurring again.
The missing files vary each time, indicating inconsistency. In addition, an error message "$digest already in progress" appears in the console log.
Although I am well-acquainted with this open source project, I am uncertain about where to begin troubleshooting this particular issue. Any insights or suggestions would be greatly appreciated.
Thank you in advance.
