Template cache should be available within the same page

1. Open Moodle
2. Ensure that the $CFG->cachejs is disabled (i.e. mdk run dev)
3. Open the browser tools to the "Network" tab
4. Open Moodle to any page
5. Wait for the page to finish loading
6. Bring up both the "Network" and "Console" tabs (Press Escape to slide the Console up usually)
7. Clear both space
8. Run the following code:

   require(['core/loadingicon'], L => L.addIconToContainer(document.querySelector('div')));

   1. Confirm that at the very top of the page you see a Loading spinner
9. Clear the "Network" tab again
10. Run the same code again
    1. Confirm that you see a second spinner
    2. Confirm that there are no new network requests

Note: On master if MDL-68528 has already been applied you will likely not see any requests on the first call either. Until that issue is integrated you will likely see:

• before first run: Some initial calls to prefetch some templates;
• with first run: one call to core_get_string
• with second run: no new calls
