Fix position of option buttons in media viewer

[jonahhw]

Describe the bug The buttons that come up when viewing an image move up each time the menu is closed and reopened

Screenshots

Between each screenshot, I tapped a few times to close and reopen the menu. Eventually, the buttons end up off the screen.

To Reproduce Steps to reproduce the behavior:

1. Go to any image
2. Tap on the screen to make the buttons go away, then tap again to make them come back. Repeat to make the effect even more dramatic.

Expected behavior The buttons come back in the same position as when they disappeared

Additional Information I think it may be related to #12, but I wasn't sure so I figured it was best to make a new issue

This appears to be a duplicate of #135

[jonahhw]

It is indeed. Should I close the issue?

I'll do it.
