Bug was fixed just on buttons that were used as example. But I see same same behavior on other buttons as was mentioned in additional info.

For example:
0. Have remote execution that succeeded.
1. Go to Monitor -> Jobs
2. Select job that succeeded
3. 'Rerun failed' is disabled
4. Click 'Rerun failed'

Another example:
0. Have remote execution that succeeded and has hosts.
1. Go to Monitor -> Jobs
2. Select job that succeeded
3. Select host from table
4. 'Cancel Job' and 'Abort Job' are disabled
5. Click on 'Cancel Job' or 'Abort Job'

Another example:
0. Have host that cannot be build
1. Navigate to host details
2. Click on disabled button 'Build'

It looks like this needs fix on whole UI, not just on buttons mentioned in examples.
