Moving towards a button hides field of view

When i was moving towards a button, I wanted to press it. But when I reached it, It hid my field of view by appearing as if I am inside it.

When I moved towards a button, i wanted to press it

After moving towards it, it turned square and hollow

Steps to reproduce:
1) place a button on a wall 2 blocks of character height
2) move towards it without pressing it
3) After moving towards it, you will appear as if you are inside the block
