Flash overlay persisting between pages?

[naps62]

I'm working on a Single Page Application written in Angular, where I'm trying to apply this module to a button

This seems to create an overlay with the flash object on top of the button. But when I click somewhere else to change the page (making the button disapear), the overlay stays there. It's still invisible, but I notice I can't over on anything where the button used to be

When using this with Bootstrap Modal, the flash overlay stays on the page after the modal is closed.

It seems that the same thing happens when using Bootstrap Tabs. :(
