Github user uce commented on the issue: https://github.com/apache/flink/pull/3189 Thanks for the PR. I also sometimes had the bad experience while testing that the cancel button was not visible. This change definitely solves it. I tested it and it works as expected. I made some screenshots and would love some feedback from other contributors before changing this. ## Wide Current: ![screen shot 2017-01-24 at 09 49 24](https://cloud.githubusercontent.com/assets/1756620/22240321/fd0736da-e21a-11e6-91a7-75b7fae8c7ba.png) This PR: ![screen shot 2017-01-24 at 09 49 37](https://cloud.githubusercontent.com/assets/1756620/22240344/01fb2e44-e21b-11e6-93f3-41b9dc9c2ad1.png) ## Narrow Current: ![screen shot 2017-01-24 at 09 49 44](https://cloud.githubusercontent.com/assets/1756620/22240356/1d18cf4c-e21b-11e6-8db3-748cecbe1eeb.png) This PR: ![screen shot 2017-01-24 at 09 49 52](https://cloud.githubusercontent.com/assets/1756620/22240358/1fdd76f6-e21b-11e6-89c9-30aa4ba05334.png)
