### Steps to reproduce

1. Login as a user with permissions to view work package comments

2. Navigate to a work package with a large number of comments E.g. https://qa.openproject-stage.com/projects/cecile-demo-project/work\_packages/3647/activity

3. OR throttle your browser network to slow a slower preset (via browser dev tools)

4. Click on the "Show everything" menu and select a different filter; "Show changes only"


### What is the buggy behavior?

* There is no feedback that the new filter request has been made

* User is still able to switch filters multiple times while waiting on first filter request


### What is the expected behavior?

Begin of the insertion* End of the insertion Begin of the deletion 1. End of the deletion Switching the filter state should transition into an intermediate loading Begin of the insertionstate (skeleton loader),End of the insertion Begin of the deletion state,End of the deletion while the new request is resolved

Begin of the insertion* End of the insertion Begin of the deletion 2. End of the deletion It should not be possible to switch to another filter while waiting on the previous one. Begin of the insertion

* Context: Necessarily only until we manage to move this outside of the bit that gets reloaded.


End of the insertion Begin of the deletion


End of the deletion <br>
