Brackets slow to shut down

[abrahammurciano]

I'm running Ubuntu 14.04 (because brackets doesn't work for me on 16, but that's besides the point) with the latest brackets as of this writing.

When I finish working, I close brackets using the Ubuntu's native close button like I normally would do in any window, but for some reason it takes really long to close. Then when I click it a second time after waiting a little, it closes immediately. Alternatively if after I click the x, I right click on the launcher icon and click quit, it also closes immediately.

I have found that clicking file>quit works totally fine and immediately closed the window.

This is really annoying... Why can't brackets do what every other​ app does and close immediately when I click x? Why do I need a different action to close brackets properly than with any other apps?

The double click to close the application is a dupe of #4611
