Loading indicator stays visible if you do many subsequent requests

[Artur-]

Description of the bug

If I e.g. send the cursor position to the server with a small delay, the loading indicator stays visible all the time. The intention of the loading indicator is to show that an operation is in progress and you need to wait for it to finish. However, that is not the case here - you should use the app like you would otherwise.

Expected behavior

Based on how it works, it seems like the time for showing the loading indicator is extended to include the following request if they happen with a small enough interval. This should maybe change so that "individual" loading indicators are used, which would probably mean that in the "send cursor position" case, no loading indicator would be shown at all

There might also be a case for explicitly marking the source of a request, e.g. a DOM listener or a @ClientCallable method, as a "background" event that shouldn't trigger a loading indicator regardless of how long it takes to process that particular request. But in that case, the loading indicator should still be shown if the current request contains both a background event and a regular event or if the current request is only with background events but there are regular events in the queue waiting for the current request to complete.
