popup asking to delete or save as draft appears just for a moment (and then disappears again) when trying to leave compose toot via back button

[horsetail-fern]

Detailed description

When I'm composing a new toot and try to use the back button (I use button navigation, not gestures) to leave the compose window, the popup, which asks if I want to save the toot as a draft or delete it, only appears for a short moment and disappears again before I can tap any of the buttons. When it disappears the compose toot window is still open, as if I never used the back button.

It seems like the popup disappears as soons as I release the back button. If I just hold it, the popup stays and I can tap one of the two options (delete/save) and everything works as expected

Using the x in the upper left corner of the compose toot window works as expected, the popup stays until I have tapped one of the options

Steps to reproduce the problem

1. Set your android to use buttons for navigation
2. Open tusky
3. start composing a toot
4. Press back button to leave the compose window
5. Popup appears just for a moment and disappears again
