It shouldn’t be an interface problem. Common reasons why requests are put into the queue are:
The rendering engine determines that resources (scripts and styles) with higher priority need to be loaded. This situation is common when loading images.
The number of TCP connections from the same source has reached the upper limit and you need to wait for new TCP resources.
You can check whether there are too many requested resources, or whether the script and style tags are positioned properly.
