Problem

Because there are not checks if ajax request is finished or not when users are editing the task, it can happen that user will leave the task from editing while some of the requests are still running or queued.

When task is left by the user, the task is also unlocked and in case of pm edit, tua is removed for this user. This will crash and throw 403 on the pending requests resulting with error window for the user.

Solution

When clicking on the UI leave task buttin, show prompt to the user that some requests are till loading.
