UI Notification of scheduled task completion

I have ran a couple of manually triggered tasks and after they have completed I am not able to re-run them without performing a refresh of the UI. The run button remains disabled.

The last log I see is:

2017-11-17 07:52:41,934+0000 INFO  [quartz-8-thread-7] *SYSTEM org.sonatype.nexus.quartz.internal.task.QuartzTaskInfo - Task 'npm' [repository.npm.reindex] state change RUNNING -> WAITING (OK)
