Issue:
I logged in as Partner and clicked on the 'Select Company' function on the top left corner to trigger the dropdown. It show the loading prompt for a while, then there was a lapse of around 10 seconds before the dropdown is shown (even though I did not click anything else). You can see the reproduction here

How it should work:
Once the loading prompt goes away, the listing should show. As such, it should be a case where we either extend the duration of the prompt, or (preferred) improve the loading speed to shorten loading time.
