Close action should work the same way as X-ing out

Currently when you "X-out" of a subapp you return to the browser (or whatever app is first). OTOH when using the close action you return to whichever subapp is closest. In some cases it's not the same. For example, when you have 3 or more subapps open.

Reproduce

• Open the Groovy app.
• Edit (open) a groovy script.
• Close using the 'X' --> returns to browser
• Edit (open) the script again.
• Close using the close button --> returns to the console
  

It's not limited to the Groovy app. The same behavior can be created in any app where 3 or more tabs are open. For example, two detail subapps open. Two assets or two pages.

Expected
Users expect the same behavior for both which is return to browser.

Actual
The close behavior returns to the closest tab and not the always the browser.
