## Description

### Steps to reproduce

*Please write down the steps to reproduce. Try to write down all necessary preconditions (what permissions do you have, are other users involved?). Example:*

1.  Have a custom action that e.g. updates the status.
2.  Have a work package for which the custom action is displayed.
3.  Go to the work package e.g. in a split view or full view 
4.  Click on the custom action - ensure the server responds slowly
5.  Click on a different field to edit it e.g. the assignee before the custom action response is done
6.  Select an assignee and submit

### What is the buggy behavior?

*Please describe the bug with as most details as possible. Example:*

  - A conflicting modifications error is displayed.
  - (the custom action button can be clicked multiple times).

### What is the expected behavior?

*Describe how the application should behave like. Example:*

1.  No error displayed. 
2.  Editing should be prevented until the response of the custom action request is back.
